Requirements
* php 4.1.0 or later (*)
If you want to display inline thumbnails of JPEGs with the
original aspect ratio, you also need GD2 support in PHP.
* MySQL 3.23.32 or newer (details);
* a web-browser (doh!).
Introduction
phpMyAdmin can manage a whole MySQL server (needs a super-user) as
well as a single database. To accomplish the latter you'll need a
properly set up MySQL user who can read/write only the desired
database. It's up to you to look up the appropriate part in the MySQL
manual.
Currently phpMyAdmin can:
* create and drop databases
* create, copy, drop, rename and alter tables
* do table maintenance
* delete, edit and add fields
* execute any SQL-statement, even batch-queries
* manage keys on fields
* load text files into tables
* create (*) and read dumps of tables
* export (*) data to CSV, XML and Latex formats
* administer multiple servers
* manage MySQL users and privileges
* check referential integrity in MyISAM tables
* using Query-by-example (QBE), create complex queries automatically
connecting required tables
* create PDF graphics of your Database layout
* search globally in a database or a subset of it
* transform stored data into any format using a set of predefined
functions, like displaying BLOB-data as image or download-link or
...
* support InnoDB tables and foreign keys (see FAQ 3.6)
* support mysqli, the improved MySQL extension (see FAQ 1.17)
* communicate in 47 different languages
(*) phpMyAdmin can compress (Zip, GZip -RFC 1952- or Bzip2 formats)
dumps and CSV exports if you use PHP4 >= 4.0.4 with Zlib support
(--with-zlib) and/or Bzip2 support (--with-bz2).
Installation
NOTE: phpMyAdmin does not apply any special security methods to the
MySQL database server. It is still the system administrator's job to
grant permissions on the MySQL databases properly. phpMyAdmin's
"Privileges" page can be used for this.
Warning for Mac users:if you are on a MacOS version before OS X,
StuffIt unstuffs with Mac formats.
So you'll have to resave as in BBEdit to Unix style ALL phpMyAdmin
scripts before uploading them to your server, as PHP seems not to like
Mac-style end of lines character ("\r").
Quick Install
1. Untar or unzip the distribution (be sure to unzip the
subdirectories): tar -xzvf phpMyAdmin_x.x.x.tar.gz in your
webserver's document root. If you don't have direct access to your
document root, put the files in a directory on your local machine,
and, after step 3, transfer the directory on your web server
using, for example, ftp.
2. Ensure that all the scripts have the appropriate owner (if PHP is
running in safe mode, having some scripts with an owner different
from the owner of other scripts will be a problem). See FAQ 4.2
for suggestions.
3. Open the file config.inc.php in your favorite editor and change
the values for host, user, password and authentication mode to fit
your environment. Here, "host" means the MySQL server. Also insert
the correct value for $cfg['PmaAbsoluteUri']. Have a look at
Configuration section for an explanation of all values.
4. It is recommended that you protect the directory in which you
installed phpMyAdmin (unless it's on a closed intranet, or you
wish to use HTTP or cookie authentication), for example with
HTTP-AUTH (in a .htaccess file). See the multi-user sub-section of
the FAQ for additional information, especially FAQ 4.4.
5. Open the file <www.your-host.com>/<your-install-dir>/index.php in
your browser. phpMyAdmin should now display a welcome screen and
your databases, or a login dialog if using HTTP or cookie
authentication mode.
Linked-tables infrastructure
For a whole set of new features (bookmarks, comments, SQL-history,
PDF-generation, field contents transformation, etc.) you need to
create a set of special tables. Those tables can be located in your
own database, or in a central database for a multi-user installation
(this database would then be accessed by the controluser, so no other
user should have rights to it).
Please look at your scripts/ directory, where you should find a file
called create_tables.sql. (If you are using a Windows server, pay
special attention to FAQ 1.23).
If your MySQL server's version is 4.1.2 or later, please use
create_tables_mysql_4_1_2+.sql instead, for a new installation.
If you already had this infrastructure and upgraded to MySQL 4.1.2 or
later, please use upgrade_tables_mysql_4_1_2+.sql.
You can use your phpMyAdmin to create the tables for you. Please be
aware that you may need special (administrator) privileges to create
the database and tables, and that the script may need some tuning,
depending on the database name.
After having imported the create_tables.sql file, you should specify
the table names in your config.inc.php file. The directives used for
that can be found in the Configuration section. You will also need to
have a controluser with the proper rights to those tables (see section
Using authentication modes below).
Upgrading from an older version
* You can safely copy your older config.inc.php over a new one, if
you can live with default values for possible new parameters (you
can check release notes to see what new features were added). This
compatibility will stay for long time, current version supports
importing config files from 2.2 and maybe even older (nobody has
tried that).
Using authentication modes
* HTTP and cookie authentication modes are recommended in a
multi-user environment where you want to give users access to
their own database and don't want them to play around with others.
Nevertheless be aware that MS Internet Explorer seems to be really
buggy about cookies, at least till version 6. And PHP 4.1.1 is
also a bit buggy in this area!
Even in a single-user environment, you might prefer to use HTTP or
cookie mode so that your user/password pair are not in clear in
the configuration file.
* HTTP and cookie authentication modes are more secure: the MySQL
password does not need to be set in the phpMyAdmin configuration
file (except for the "controluser" -see the Configuration
section).
However, keep in mind that the password travels in plain text,
unless you are using the HTTPS protocol.
In cookie mode, the password is stored, encrypted with the
blowfish algorithm, in a temporary cookie.
* For 'HTTP' and 'cookie' modes, phpMyAdmin needs a controluser that
has only the SELECT privilege on the mysql.user (all columns
except "Password"), mysql.db (all columns), mysql.host (all
columns) and mysql.tables_priv (all columns except "Grantor" &
"Timestamp") tables.
You must specify the details for the controluser in the
config.inc.php file under the $cfg['Servers'][$i]['controluser']&
$cfg['Servers'][$i]['controlpass'] settings.
The following example assumes you want to use pma as the
controluser and pmapass as the controlpass, but this is only an
example: use something else in your file!
Of course you have to replace localhost by the webserver's host if
it's not the same as the MySQL server's one.
GRANT USAGE ON mysql.* TO 'pma'@'localhost' IDENTIFIED BY 'pmapass';
GRANT SELECT (
Host, User, Select_priv, Insert_priv, Update_priv, Delete_priv,
Create_priv, Drop_priv, Reload_priv, Shutdown_priv, Process_priv,
File_priv, Grant_priv, References_priv, Index_priv, Alter_priv,
Show_db_priv, Super_priv, Create_tmp_table_priv, Lock_tables_priv,
Execute_priv, Repl_slave_priv, Repl_client_priv
) ON mysql.user TO 'pma'@'localhost';
GRANT SELECT ON mysql.db TO 'pma'@'localhost';
GRANT SELECT ON mysql.host TO 'pma'@'localhost';
GRANT SELECT (Host, Db, User, Table_name, Table_priv, Column_priv)
ON mysql.tables_priv TO 'pma'@'localhost';
If you are using an old MySQL version (below 4.0.2), please
replace the first GRANT SELECT query by this one:
GRANT SELECT (
Host, User, Select_priv, Insert_priv, Update_priv, Delete_priv,
Create_priv, Drop_priv, Reload_priv, Shutdown_priv, Process_priv,
File_priv, Grant_priv, References_priv, Index_priv, Alter_priv
) ON mysql.user TO 'pma'@'localhost';
... and if you want to use the many new relation and bookmark
features:
GRANT SELECT, INSERT, UPDATE, DELETE ON <pma_db>.* TO 'pma'@'localhost';
(this of course requires you to have a special DB for phpMyAdmin,
the contents will be explained later)
Of course, the above queries only work if your MySQL version
supports the GRANT command. This is the case since 3.22.11.
* Then each of the true users should be granted a set of privileges
on a set of particular databases. Normally you shouldn't give
global privileges to an ordinary user, unless you understand the
impact of those privileges (for example, you are creating a
superuser).
For example, to grant the user real_user with all privileges on
the database user_base:
GRANT ALL PRIVILEGES ON user_base.* TO 'real_user'@localhost
IDENTIFIED BY 'real_password';
What the user may now do is controlled entirely by the MySQL user
management system.
With HTTP or cookie authentication mode, you don't need to fill
the user/password fields inside the $cfg['Servers'] array.
'http' authentication mode
* Was called 'advanced' in versions before 2.2.3.
* Introduced in 1.3.0, it uses Basic HTTP authentication method and
allows you to login as any valid MySQL user.
* Is only supported with PHP running as an Apache module, not with
CGI.
* See also FAQ 4.4 about not using the .htaccess mechanism along
with 'http' authentication mode.
'cookie' authentication mode
* You can use this method as a replacement for the HTTP
authentication (for example, if you're running IIS).
* Obviously, the user must enable cookies in the browser.
* With this mode, the user can truly logout of phpMyAdmin and login
back with the same username.
* If you want to login to arbitrary server see
$cfg['AllowArbitraryServer'] directive.
'config' authentication mode
* This mode is the less secure one because it requires you to fill
the $cfg['Servers'][$i]['user'] and
$cfg['Servers'][$i]['password'] fields.
But you don't need to setup a "controluser" here: using the
$cfg['Servers'][$i]['only_db'] might be enough.
* In the ISP FAQ section, there is an entry explaining how to
protect your configuration file.
* For additional security in this mode, you may wish to consider the
Host authentication $cfg['Servers'][$i]['AllowDeny']['order'] and
$cfg['Servers'][$i]['AllowDeny']['rules'] configuration
directives.
Configuration
Warning for Mac users: PHP seems not to like Mac end of lines
character ("\r"). So ensure you choose the option that allows to use
the *nix end of line character ("\n") in your text editor before
registering a script you have modified.
Configuration note: Almost all configurable data is placed in
config.inc.php. The parameters which relate to design (like colors)
are placed in themes/themename/layout.inc.php. You might also want to
modify config.footer.inc.php and config.header.inc.php files to add
your site specific code to be included on start and end of each page.
$cfg['PmaAbsoluteUri'] string
Sets here the complete URL (with full path) to your phpMyAdmin
version. E.g.
http://www.your_web.net/path_to_your_phpMyAdmin_directory/.
phpMyAdmin needs this setting, because of requirements of the
HTTP protocol, explained in RFC2616, section 14.30.
Don't forget the slash at the end of your URL. The URL must
contain characters that are valid for a URL, and on some
servers, the path is case-sensitive.
Starting with version 2.3.0, you can try to leave this
parameter empty, because the program tries to auto-detect its
proper value. Additional details are in the configuration file.
$cfg['PmaAbsoluteUri_DisableWarning'] boolean
By default, when you leave $cfg['PmaAbsoluteUri'] empty, and
the system detects your absolute URI automatically, we display
a warning to remind you. If you have tested the automatic
detection, and it works perfectly for your setup, then you can
set this variable to squelch the warning.
$cfg['PmaNoRelation_DisableWarning'] boolean
Starting with version 2.3.0 phpMyAdmin offers a lot of features
to work with master / foreign - tables (see
$cfg['Servers'][$i]['pmadb']).
If you tried to set this up and it does not work for you, have
a look on the "Structure" page of one database where you would
like to use it. You will find a link that will analyze why
those features have been disabled.
If you do not want to use those features set this variable to
TRUE to stop this message from appearing.
$cfg['blowfish_secret'] string
Starting with version 2.5.2, the 'cookie' auth_type uses
blowfish algorithm to encrypt the password.
If at least one server configuration uses 'cookie' auth_type,
enter here a passphrase of your choice that will be used by
blowfish.
$cfg['Servers'] array
Since version 1.4.2, phpMyAdmin supports the administration of
multiple MySQL servers. Therefore, a $cfg['Servers']-array has
been added which contains the login information for the
different servers. The first $cfg['Servers'][$i]['host']
contains the hostname of the first server, the second
$cfg['Servers'][$i]['host'] the hostname of the second server,
etc. If you have only one server to administer, simply leave
free the hostname of the other $cfg['Server']-entries.
$cfg['Servers'][$i]['host'] string
The hostname or IP address of your $i-th MySQL-server. E.g.
localhost.
$cfg['Servers'][$i]['port'] string
The port-number of your $i-th MySQL-server. Default is 3306
(leave blank). If you use "localhost" as the hostname, MySQL
ignores this port number and connects with the socket, so if
you want to connect to a port different from the default port,
use "127.0.0.1" or the real hostname in
$cfg['Servers'][$i]['host'].
$cfg['Servers'][$i]['socket'] string
The path to the socket to use. Leave blank for default.
To use the socket feature you must run PHP 3.0.10 or more.
$cfg['Servers'][$i]['connect_type'] string
What type connection to use with the MySQL server. Your options
are 'socket' & 'tcp'. It defaults to 'tcp' as that is nearly
guaranteed to be available on all MySQL servers, while sockets
are not supported on some platforms.
To use the socket mode, your MySQL server must be on the same
machine as the Web server.
$cfg['Servers'][$i]['extension'] string
What php MySQL extension to use for the connection. Valid
options are:
mysql : The classic MySQL extension. This is the recommended
and default method at this time.
mysqli : The improved MySQL extension. This extension became
available with php 5.0.0 and is the recommended way to connect
to a server running MySQL 4.1.x.
Note: phpMyAdmin's MySQL 4.1 support is experimental!
$cfg['Servers'][$i]['compress'] boolean
Whether to use a compressed protocol for the MySQL server
connection or not (experimental).
This feature requires PHP >= 4.3.0.
$cfg['Servers'][$i]['controluser'] string
$cfg['Servers'][$i]['controlpass'] string
This special account is used for 2 distinct purposes: to make
possible a multi-user installation (http or cookie
authentication mode) and also for all relational features (see
$cfg['Servers'][$i]['pmadb']).
When using HTTP or cookie authentication modes (or 'config'
authentication mode since phpMyAdmin 2.2.1), you need to supply
the details of a MySQL account that has SELECT privilege on the
mysql.user (all columns except "Password"), mysql.db (all
columns) & mysql.tables_priv (all columns except "Grantor" &
"Timestamp") tables. This account is used to check what
databases the user will see at login.
Please see the install section on "Using authentication modes"
for more information.
Note that if you try login to phpMyAdmin with this
"controluser", you could get some errors, depending the exact
privileges you gave to the "controluser". phpMyAdmin does not
support a direct login with the "controluser".
In versions before 2.2.5, those were called "stduser/stdpass".
$cfg['Servers'][$i]['auth_type'] string ['http'|'cookie'|'config']
Whether config or cookie or http authentication should be used
for this server.
+ 'config' authentication ($auth_type = 'config') is the plain
old way: username and password are stored in config.inc.php.
+ 'cookie' authentication mode ($auth_type = 'cookie') as
introduced in 2.2.3 allows you to log in as any valid MySQL
user with the help of cookies. Log name and password are
stored in cookies during the session and password is deleted
when it ends. This can also allow you to login in arbitrary
server if $cfg['AllowArbitraryServer'] enabled.
+ 'http' authentication (was called 'advanced' in older
versions) ($auth_type = 'http') as introduced in 1.3.0 allows
you to log in as any valid MySQL user via HTTP-Auth.
Please see the install section on "Using authentication modes"
for more information.
$cfg['Servers'][$i]['user'] string
$cfg['Servers'][$i]['password'] string
The user/password-pair which phpMyAdmin will use to connect to
this MySQL-server. This user/password pair is not needed when
HTTP or cookie authentication is used, and should be empty.
$cfg['Servers'][$i]['only_db'] string or array
If set to a (an array of) database name(s), only this (these)
database(s) will be shown to the user. Since phpMyAdmin 2.2.1,
this/these database(s) name(s) may contain MySQL wildcards
characters ("_" and "%"): if you want to use literal instances
of these characters, escape them (I.E. use 'my\_db' and not
'my_db').
This setting is an efficient way to lower the server load since
the latter does not need to send MySQL requests to build the
available database list. But it does not replace the privileges
rules of the MySQL database server. If set, it just means only
these databases will be displayed but not that all other
databases can't be used.
An example of using more that one database:
$cfg['Servers'][$i]['only_db'] = array('db1', 'db2');
As of phpMyAdmin 2.5.5 the order inside the array is used for
sorting the databases in the left frame, so that you can
individually arrange your databases.
If you want to have certain databases at the top, but don't
care about the others, you do not need to specify all other
databases. Use: $cfg['Servers'][$i]['only_db'] = array('db3',
'db4', '*'); instead to tell phpMyAdmin that it should display
db3 and db4 on top, and the rest in alphabetic order.
$cfg['Servers'][$i]['verbose'] string
Only useful when using phpMyAdmin with multiple server entries.
If set, this string will be displayed instead of the hostname
in the pull-down menu on the main page. This can be useful if
you want to show only certain databases on your system, for
example.
$cfg['Servers'][$i]['pmadb'] string
The name of the database containing the linked-tables
infrastructure.
See the Linked-tables infrastructure section in this document
to see the benefits of this infrastructure, and for a quick way
of creating this database and the needed tables.
If you are the only user of this phpMyAdmin installation, you
can use your current database to store those special tables; in
this case, just put your current database name in
$cfg['Servers'][$i]['pmadb']. For a multi-user installation,
set this parameter to the name of your central database
containing the linked-tables infrastructure.
$cfg['Servers'][$i]['bookmarktable'] string
Since release 2.2.0 phpMyAdmin allows to bookmark queries. This
can be useful for queries you often run.
To allow the usage of this functionality:
+ set up pmadb and the linked-tables infrastructure
+ enter the table name in $cfg['Servers'][$i]['bookmarktable']
$cfg['Servers'][$i]['relation'] string
Since release 2.2.4 you can describe, in a special 'relation'
table, which field is a key in another table (a foreign key).
phpMyAdmin currently uses this to
+ make clickable, when you browse the master table, the data
values that point to the foreign table;
+ display in an optional tool-tip the "display field" when
browsing the master table, if you move the mouse to a column
containing a foreign key (use also the 'table_info' table);
(see FAQ 6.7)
+ in edit/insert mode, display a drop-down list of possible
foreign keys (key value and "display field" are shown)
(see FAQ 6.21)
+ display links on the table properties page, to check
referential integrity (display missing foreign keys) for each
described key;
+ in query-by-example, create automatic joins (see FAQ 6.6)
+ enable you to get a PDF schema of your database (also uses
the table_coords table).
The keys can be numeric or character.
To allow the usage of this functionality:
+ set up pmadb and the linked-tables infrastructure
+ put the relation table name in
$cfg['Servers'][$i]['relation']
+ now as normal user open phpMyAdmin and for each one of your
tables where you want to use this feature, click
"Structure/Relation view/" and choose foreign fields.
Please note that in the current version, master_db must be the
same as foreign_db. Those fields have been put in future
development of the cross-db relations.
$cfg['Servers'][$i]['table_info'] string
Since release 2.3.0 you can describe, in a special 'table_info'
table, which field is to be displayed as a tool-tip when moving
the cursor over the corresponding key.
This configuration variable will hold the name of this special
table. To allow the usage of this functionality:
+ set up pmadb and the linked-tables infrastructure
+ put the table name in $cfg['Servers'][$i]['table_info']
+ then for each table where you want to use this feature, click
"Structure/Relation view/Choose field to display" to choose
the field.
Usage tip: Display field.
$cfg['Servers'][$i]['table_coords'] string
$cfg['Servers'][$i]['pdf_pages'] string
Since release 2.3.0 you can have phpMyAdmin create PDF pages
showing the relations between your tables. To do this it needs
two tables "pdf_pages" (storing information about the available
PDF pages) and "table_coords" (storing coordinates where each
table will be placed on a PDF schema output).
You must be using the "relation" feature.
To allow the usage of this functionality:
+ set up pmadb and the linked-tables infrastructure
+ put the correct table names in
$cfg['Servers'][$i]['table_coords'] and
$cfg['Servers'][$i]['pdf_pages']
Usage tips: PDF output.
$cfg['Servers'][$i]['column_info'] string
Since release 2.3.0 you can store comments to describe each
column for each table. These will then be shown on the
"printview".
Starting with release 2.5.0, comments are consequently used on
the table property pages and table browse view, showing up as
tool-tips above the column name (properties page) or embedded
within the header of table in browse view. They can also be
shown in a table dump. Please see the relevant configuration
directives later on.
Also new in release 2.5.0 is a MIME-transformation system which
is also based on the following table structure. See
Transformations for further information. To use the
MIME-transformation system, your column_info table has to have
the three new fields 'mimetype', 'transformation',
'transformation_options'.
To allow the usage of this functionality:
+ set up pmadb and the linked-tables infrastructure
+ put the table name in $cfg['Servers'][$i]['column_info']
+ to update your PRE-2.5.0 Column_comments Table use this:
ALTER TABLE `pma_column_comments`
ADD `mimetype` VARCHAR( 255 ) NOT NULL ,
ADD `transformation` VARCHAR( 255 ) NOT NULL ,
ADD `transformation_options` VARCHAR( 255 ) NOT NULL ;
and remember that the Variable in config.inc.php has been
renamed from
$cfg['Servers'][$i]['column_comments'] to
$cfg['Servers'][$i]['column_info']
$cfg['Servers'][$i]['history'] string
Since release 2.5.0 you can store your SQL history, which means
all queries you entered manually into the phpMyAdmin interface.
If you don't want to use a table- based history, you can use
the JavaScript-based history. Using that, all your history
items are deleted when closing the window.
Using $cfg['QueryHistoryMax'] you can specify an amount of
history items you want to have on hold. On every login, this
list gets cut to the maximum amount.
The query history is only available if you use the
JavaScript-based query window, see $cfg['QueryFrame'].
To allow the usage of this functionality:
+ set up pmadb and the linked-tables infrastructure
+ put the table name in $cfg['Servers'][$i]['history']
$cfg['Servers'][$i]['verbose_check'] string
Because release 2.5.0 introduced the new MIME-transformation
support, the column_info table got enhanced with three new
fields. If the above variable is set to TRUE (default)
phpMyAdmin will check if you have the latest table structure
available. If not, it will emit a warning to the superuser.
You can disable this checking behavior by setting the variable
to false, which should offer a performance increase.
Recommended to set to FALSE, when you are sure, your table
structure is up to date.
$cfg['Servers'][$i]['AllowDeny']['order'] string
If your rule order is empty, then IP authentication is
disabled.
If your rule order is set to 'deny,allow' then the system
applies all deny rules followed by allow rules. Access is
allowed by default. Any client which does not match a Deny
command or does match an Allow command will be allowed access
to the server.
If your rule order is set to 'allow,deny' then the system
applies all allow rules followed by deny rules. Access is
denied by default. Any client which does not match an Allow
directive or does match a Deny directive will be denied access
to the server.
If your rule order is set to 'explicit', the authentication is
performed in a similar fashion to rule order 'deny,allow', with
the added restriction that your host/username combination must
be listed in the allow rules, and not listed in the deny rules.
This is the most secure means of using Allow/Deny rules, and
was available in Apache by specifying allow and deny rules
without setting any order.
$cfg['Servers'][$i]['AllowDeny']['rules'] array of strings
The general format for the rules is as such:
<'allow' | 'deny'> <username> [from] <ipmask>
If you wish to match all users, it is possible to use a '%' as
a wildcard in the username field.
There are a few shortcuts you can use in the ipmask field as
well:
'all' -> 0.0.0.0/0
'localhost' -> 127.0.0.1/8
Having an empty rule list is equivalent to either using 'allow
% from all' if your rule order is set to 'deny,allow' or 'deny
% from all' if your rule order is set to 'allow,deny' or
'explicit'.
For the IP matching system, the following work:
xxx.xxx.xxx.xxx (an exact IP address)
xxx.xxx.xxx.[yyy-zzz] (an IP address range)
xxx.xxx.xxx.xxx/nn (CIDR, Classless Inter-Domain Routing type
IP addresses)
But the following does not work:
xxx.xxx.xxx.xx[yyy-zzz] (partial IP address range)
$cfg['ServerDefault'] integer
If you have more than one server configured, you can set
$cfg['ServerDefault'] to any one of them to autoconnect to that
server when phpMyAdmin is started, or set it to 0 to be given a
list of servers without logging in.
If you have only one server configured, $cfg['ServerDefault']
MUST be set to that server.
$cfg['OBGzip'] string/boolean
Defines whether to use GZip output buffering for increased
speed in HTTP transfers.
Set to true/false for enabling/disabling. When set to 'auto'
(string), phpMyAdmin tries to enable output buffering and will
automatically disable it, if your browser has some problems
with buffering. IE6 with a certain patch is known to cause data
corruption having enabled buffering.
$cfg['PersistentConnections'] boolean
Whether persistent connections should be used or not
(mysql_connect or mysql_pconnect).
$cfg['ExecTimeLimit'] integer [number of seconds]
Set the number of seconds a script is allowed to run. If
seconds is set to zero, no time limit is imposed.
This setting is used while importing/exporting dump files but
has no effect when PHP is running in safe mode.
$cfg['SkipLockedTables'] boolean
Mark used tables and make it possible to show databases with
locked tables (since 3.23.30).
$cfg['ShowSQL'] boolean
Defines whether SQL-queries generated by phpMyAdmin should be
displayed or not.
$cfg['AllowUserDropDatabase'] boolean
Defines whether normal users (non-administrator) are allowed to
delete their own database or not. If set as FALSE, the link
"Drop Database" will not be shown, and even a "DROP DATABASE
mydatabase" will be rejected. Quite practical for ISP's with
many customers.
$cfg['Confirm'] boolean
Whether a warning ("Are your really sure...") should be
displayed when you're about to lose data.
$cfg['LoginCookieRecall'] boolean
Define whether the previous login should be recalled or not in
cookie authentication mode.
$cfg['UseDbSearch'] boolean
Define whether the "search string inside database" is enabled
or not.
$cfg['IgnoreMultiSubmitErrors'] boolean
Define whether phpMyAdmin will continue executing a multi-query
statement if one of the queries fails. Default is to abort
execution.
$cfg['VerboseMultiSubmit'] boolean
Define whether phpMyAdmin will output the results of each query
of a multi-query statement embedded into the SQL output as
inline comments. Defaults to TRUE.
$cfg['AllowArbitraryServer'] boolean
If enabled allows you to login to arbitrary server using cookie
auth.
NOTE: Please use this carefully, as this may allow to access
MySQL servers behind firewall where your http server is placed.
$cfg['LeftFrameLight'] boolean
Defines whether to use select-based menu and display only the
current tables in the left frame (smaller page). Only in
Non-Lightmode you can use the feature to display nested folders
using $cfg['LeftFrameTableSeparator']
$cfg['LeftFrameTableSeparator'] string
Defines a string to be used to nest table spaces. Defaults to
'__'. This means if you have tables like 'first__second__third'
this will be shown as a three-level hierarchie like: first >
second > third. If set to FALSE or empty, the feature is
disabled. NOTE: You shall not use this Separator in a table
name at the beginning or end of a table name, or multiple times
after another without any other characters in between.
$cfg['LeftFrameTableLevel'] string
Defines how many sublevels should be displayed when splitting
up tables by the above Separator.
$cfg['ShowTooltip'] boolean
Defines whether to display table comment as tool-tip in left
frame or not.
$cfg['ShowTooltipAliasDB'] boolean
If tool-tips are enabled and a DB comment is set, this will
flip the comment and the real name. That means, if you have a
table called 'user0001' and add the comment 'MyName' on it, you
will see the name 'MyName' used consequently in the left frame
and the tool-tip shows the real name of the DB.
$cfg['ShowTooltipAliasTB'] boolean/string
Same as $cfg['ShowTooltipAliasDB'], except this works for table
names. When setting this to 'nested', the Alias of the
Tablename is only used to split/nest the tables according to
the $cfg['LeftFrameTableSeparator'] directive. So only the
folder is called like the Alias, the tablename itself stays the
real tablename.
$cfg['LeftDisplayLogo'] boolean
Defines whether to display the phpMyAdmin logo at the top of
the left frame or not. Defaults to TRUE.
$cfg['LeftDisplayServers'] boolean
Defines whether to display a server choice at the top of the
left frame or not. Defaults to FALSE.
$cfg['DisplayServersList'] boolean
Defines whether to display this server choice as links instead
of in a drop-down. Defaults to FALSE (drop-down).
$cfg['ShowStats'] boolean
Defines whether to display space usage and statistics about
databases and tables or not.
Note that statistics requires at least MySQL 3.23.3 and that,
at this date, MySQL doesn't return such information for
Berkeley DB tables.
$cfg['ShowMysqlInfo'] boolean
$cfg['ShowMysqlVars'] boolean
$cfg['ShowPhpInfo'] boolean
$cfg['ShowChgPassword'] boolean
Defines whether to display the "MySQL runtime information",
"MySQL system variables", "PHP information" and "Change
password " links or not for simple users at the starting main
(right) frame. This setting does not check MySQL commands
entered directly.
Please note that to block the usage of phpinfo() in scripts,
you have to put this in your php.ini:
disable_functions = phpinfo()
Also note that enabling the "Change password " link has no
effect with "config" authentication mode: because of the hard
coded password value in the configuration file, end users can't
be allowed to change their passwords.
$cfg['SuggestDBName'] boolean
Defines whether to suggest a database name on the "Create
Database" form or to keep the textfield empty.
$cfg['ShowBlob'] boolean
Defines whether BLOB fields are shown when browsing a table's
content or not.
$cfg['NavigationBarIconic'] boolean
Defines whether navigation bar buttons contain text or symbols
only.
$cfg['ShowAll'] boolean
Defines whether an user should be displayed a "show all
(records)" button in browse mode or not.
$cfg['MaxRows'] integer
Number of rows displayed when browsing a result set. If the
result set contains more rows, Previous/Next links will be
shown.
$cfg['Order'] string [DESC|ASC|SMART]
Defines whether fields are displayed in ascending (ASC) order,
in descending (DESC) order or in a "smart" (SMART) order - I.E.
descending order for fields of type TIME, DATE, DATETIME &
TIMESTAMP, ascending order else- by default.
$cfg['ProtectBinary'] boolean or string
Defines whether BLOB or BINARY fields are protected from
edition when browsing a table's content or not. Valid values
are:
- FALSE to allow edition of all fields;
- blob to allow edition of all fields except BLOBS;
- all to disallow edition of all BINARY or BLOB fields.
$cfg['ShowFunctionFields'] boolean
Defines whether MySQL functions fields should be displayed or
not in edit/insert mode.
$cfg['CharEditing'] string
Defines which type of editing controls should be used for CHAR
and VARCHAR fields. Possible values are:
+ input - this allows to limit size of text to size of field in
MySQL, but has problems with newlines in fields
+ textarea - no problems with newlines in fields, but also no
length limitations
Default is old behavior so input.
$cfg['ZipDump'] boolean
$cfg['GZipDump'] boolean
$cfg['BZipDump'] boolean
Defines whether to allow the use of zip/GZip/BZip2 compression
when creating a dump file or not.
$cfg['CompressOnFly'] boolean
Defines whether to allow on the fly compression for GZip/BZip2
compressed exports. This doesn't affect smaller dumps and
allows to create larger dumps, that won't fit otherwise in
memory due to php memory limit. Produced files contain more
GZip/BZip2 headers, but all normal programs handle this
correctly.
$cfg['LightTabs'] string
If set to True, do use less graphically intense tabs on the top
of the mainframe.
$cfg['PropertiesIconic'] string
If set to True, will display icons instead of text for db and
table properties links (like 'Browse', 'Select', 'Insert',
...).
Can be set to 'both' if you want icons AND text.
When set to False, will only show text.
$cfg['PropertiesNumColumns'] integer
How many columns will be utilized to display the tables on the
database property view? Default is 1 column. When setting this
to a value larger than 1, the type of the database will be
omitted for more display space.
$cfg['DefaultTabServer'] string
Defines the tab displayed by default on server view. Possible
values: "main.php" (recommended for multi-user setups),
"server_databases.php", "server_status.php",
"server_variables.php", "server_privileges.php" or
"server_processlist.php".
$cfg['DefaultTabDatabase'] string
Defines the tab displayed by default on database view. Possible
values: "db_details_structure.php", "db_details.php" or
"db_search.php".
$cfg['DefaultTabTable'] string
Defines the tab displayed by default on table view. Possible
values: "tbl_properties_structure.php", "tbl_properties.php",
"tbl_select.php" or "tbl_change.php".
$cfg['MySQLManualBase'] string
If set to an URL which points to the MySQL documentation (type
depends on $cfg['MySQLManualType']), appropriate help links are
generated.
See MySQL Documentation page for more information about MySQL
manuals and their types.
$cfg['MySQLManualType'] string

+ old - old style used in phpMyAdmin 2.3.0 and earlier
+ searchable - "Searchable, with user comments"
+ chapters - "HTML, one page per chapter"
+ big - "HTML, all on one page"
+ none - do not show documentation links
$cfg['DefaultLang'] string
Defines the default language to use, if not browser-defined or
user-defined.
See the select_lang.inc.php script to know the valid values for
this setting.
$cfg['Lang'] string
Force: always use this language (must be defined in the
select_lang.inc.php script).
$cfg['DefaultCharset'] string
Default character set to use for recoding of MySQL queries.
This must be enabled and it's described by
$cfg['AllowAnywhereRecoding'] option.
You can give here any character set which is in
$cfg['AvailableCharsets'] array and this is just default
choice, user can select any of them.
$cfg['AllowAnywhereRecoding'] boolean
Allow character set recoding of MySQL queries. You need recode
or iconv support (compiled in or module) in PHP to allow MySQL
queries recoding and used language file must have it enabled
(by default only these which are in Unicode, just to avoid
losing some characters).
$cfg['RecodingEngine'] string
You can select here which functions will be used for character
set conversion. Possible values are:
+ auto - automatically use available one (first is tested
iconv, then recode)
+ iconv - use iconv or libiconv functions
+ recode - use recode_string function
Default is auto.
$cfg['IconvExtraParams'] string
Specify some parameters for iconv used in charset conversion.
See iconv documentation for details.
$cfg['AvailableCharsets'] array
Available character sets for MySQL conversion. You can add your
own (any of supported by recode/iconv) or remove these which
you don't use. Character sets will be shown in same order as
here listed, so if you frequently use some of these move them
to the top.
$cfg['GD2Available'] string
Specifies whether GD >= 2 is available. If yes it can be used
for MIME transformations.
Possible values are:
+ auto - automatically detect, this is a bit expensive
operation for php < 4.3.0 so it is preferred to change this
according to your server real possibilities
+ yes - GD 2 functions can be used
+ no - GD 2 function cannot be used
Default is auto.
$cfg['LeftWidth'] integer
Left frame width in pixel. See themes/themename/layout.inc.php.
$cfg['LeftBgColor'] string [HTML color]
$cfg['RightBgColor'] string [HTML color]
The background colors (HTML) used for both the frames. See
themes/themename/layout.inc.php.
$cfg['RightBgImage'] string
The URI of the background image used for the right frame. It
must be an absolute URI. See themes/themename/layout.inc.php.
$cfg['LeftPointerColor'] string [HTML color]
The color (HTML) used for the pointer in the left frame (does
not work with Netscape 4). See themes/themename/layout.inc.php.
$cfg['LeftPointerEnable'] boolean
A value of TRUE activates the left pointer (when LeftFrameLight
is FALSE).
$cfg['Border'] integer
The size of a table's border. See
themes/themename/layout.inc.php.
$cfg['ThBgcolor'] string [HTML color]
The color (HTML) used for table headers. See
themes/themename/layout.inc.php.
$cfg['BgcolorOne'] string [HTML color]
The color (HTML) #1 for table rows. See
themes/themename/layout.inc.php.
$cfg['BgcolorTwo'] string [HTML color]
The color (HTML) #2 for table rows. See
themes/themename/layout.inc.php.
$cfg['BrowsePointerColor'] string [HTML color]
$cfg['BrowseMarkerColor'] string [HTML color]
The colors (HTML) uses for the pointer and the marker in browse
mode (does not work with Netscape 4).
The former feature highlights the row over which your mouse is
passing and the latter lets you visually mark/unmark rows by
clicking on them.
See themes/themename/layout.inc.php.
$cfg['BrowsePointerEnable'] boolean
Whether to activate the browse pointer or not.
$cfg['BrowseMarkerEnable'] boolean
Whether to activate the browse marker or not.
$cfg['TextareaCols'] integer
$cfg['TextareaRows'] integer
$cfg['CharTextareaCols'] integer
$cfg['CharTextareaRows'] integer
Number of columns and rows for the textareas.
This value will be emphasized (*2) for SQL query textareas and
(*1.25) for SQL textareas inside the query window.
The Char* values are used for CHAR and VARCHAR editing (if
configured via $cfg['CharEditing']).
$cfg['LongtextDoubleTextarea'] boolean
Defines whether textarea for LONGTEXT fields should have double
size.
$cfg['TextareaAutoSelect'] boolean
Defines if the whole textarea of the query box will be selected
on click.
$cfg['CtrlArrowsMoving'] boolean
Enable Ctrl+Arrows moving between fields when editing?
$cfg['LimitChars'] integer
Maximal number of Chars showed in any non-numeric field on
browse view. Can be turned off by a toggle button on the browse
page.
$cfg['ModifyDeleteAtLeft'] boolean
$cfg['ModifyDeleteAtRight'] boolean
Defines the place where modify and delete links would be put
when tables contents are displayed (you may have them displayed
both at the left and at the right). "Left" and "right" are
parsed as "top" and "bottom" with vertical display mode.
$cfg['DefaultDisplay'] string
$cfg['HeaderFlipType'] string
There are 3 display modes: horizontal, horizontalflipped and
vertical. Define which one is displayed by default. The first
mode displays each row on a horizontal line, the second rotates
the headers by 90 degrees, so you can use descriptive headers
even though fields only contain small values and still print
them out. The vertical mode sorts each row on a vertical
lineup.
The HeaderFlipType can be set to 'css' or 'faked'. When using
'css' the rotation of the header for horizontalflipped is done
via CSS. If set to 'faked' PHP does the transformation for you,
but of course this does not look as good as CSS.
$cfg['DefaultPropDisplay'] string
When editing/creating new columns in a table all fields
normally get lined up one field a line. (default:
'horizontal'). If you set this to 'vertical' you can have each
field lined up vertically beneath each other. You can save up a
lot of place on the horizontal direction and no longer have to
scroll.
$cfg['ShowBrowseComments'] boolean
$cfg['ShowPropertyComments'] boolean
By setting the corresponding variable to TRUE you can enable
the display of column comments in Browse or Property display.
In browse mode, the comments are show inside the header. In
property mode, comments are displayed using a CSS-formatted
dashed-line below the name of the field. The comment is shown
as a tool-tip for that field.
$cfg['UploadDir'] string
The name of the directory, where SQL files have been uploaded
by other means than phpMyAdmin (for example, ftp). Those files
are available under a drop-down box when you click the database
name, then the SQL tab.
Please note that the file names must have the suffix ".sql" (or
".sql.bz2" or ".sql.gz" if support for compressed formats is
enabled).
This feature is useful when your file is too big to be uploaded
via HTTP, or when file uploads are disabled in PHP.
Please note that if PHP is running in safe mode, this directory
must be owned by the same user as the owner of the phpMyAdmin
scripts.
$cfg['docSQLDir'] string
The name of the directory, where docSQL files can be uploaded
for import into phpMyAdmin.
Please note that if PHP is running in safe mode, this directory
must be owned by the same user as the owner of the phpMyAdmin
scripts.
$cfg['SaveDir'] string
The name of the directory, where dumps can be saved.
Please note that the directory has to be writable for user
running webserver.
Please note that if PHP is running in safe mode, this directory
must be owned by the same user as the owner of the phpMyAdmin
scripts.
$cfg['TempDir'] string
The name of the directory, where temporary files can be stored.
This is needed for native MS Excel export, see FAQ 6.23
$cfg['Export'] array
In this array are defined default parameters for export, names
of items are similar to texts seen on export page, so you can
easily identify what they mean.
$cfg['RepeatCells'] integer
Repeat the headers every X cells, or 0 to deactivate.
$cfg['QueryFrame'] boolean
$cfg['QueryFrameJS'] boolean
$cfg['QueryWindowWidth'] integer
$cfg['QueryWindowHeight'] integer
$cfg['QueryHistoryDB'] boolean
$cfg['QueryWindowDefTab'] string
$cfg['QueryHistoryMax'] integer
All those variables affect the query box feature. When
$cfg['QueryFrame'] is set to true, a link or icon is displayed
on the left panel. Clicking on it opens the query box, a direct
interface to enter SQL queries.
When $cfg['QueryFrameJS'] is set to true, clicking on that link
opens the query box, a new custom sized browser window
($cfg['QueryWindowWidth'], $cfg['QueryWindowWidth'] - both
integers for the size in pixels). Also, a click on [Edit] from
the results page (in the "Showing Rows" section) opens the
query box and puts the current query inside it. If set to
false, clicking on the link only opens the SQL input in the
main frame.
The usage of the JavaScript query window is recommended if you
have a JavaScript enabled browser. Basic functions are used to
exchange quite a few variables, so most 4th generation browsers
should be capable to use that feature. It currently is only
tested with Internet Explorer 6 and Mozilla 1.x.
If $cfg['QueryHistoryDB'] is set to TRUE, all your Queries are
logged to a table, which has to be created by you (see
$cfg['Servers'][$i]['history']). If set to FALSE, all your
queries will be appended to the form, but only as long as your
window is opened they remain saved.
When using the JavaScript based query window, it will always
get updated when you click on a new table/db to browse and will
focus if you click on "Edit SQL" after using a query. You can
suppress updating the query window by checking the box "Do not
overwrite this query from outside the window" below the query
textarea. Then you can browse tables/databases in the
background without losing the contents of the textarea, so this
is especially useful when composing a query with tables you
first have to look in. The checkbox will get automatically
checked whenever you change the contents of the textarea.
Please uncheck the button whenever you definitely want the
query window to get updated even though you have made
alterations.
If $cfg['QueryHistoryDB'] is set to TRUE you can specify the
amount of saved history items using $cfg['QueryHistoryMax'].
The query window also has a custom tabbed look to group the
features. Using the variable $cfg['QueryWindowDefTab'] you can
specify the default tab to be used when opening the query
window. It can be set to either 'sql', 'files', 'history' or
'full'.
$cfg['BrowseMIME'] boolean
Enable MIME-transformations.
$cfg['MaxExactCount'] integer
Determines for how large tables phpMyAdmin should get exact row
count by SELECT COUNT. If approximate row count is smaller than
this value, SELECT COUNT will be used, otherwise only value
returned by SHOW TABLE STATUS.
$cfg['WYSIWYG-PDF'] boolean
Utilizes a WYSIWYG editing control to easily place elements of
a PDF page. By clicking on the button 'toggle scratchboard' on
the page where you edit x/y coordinates of those elements you
can activate a scratchboard where all your elements are placed.
By clicking on an element, you can move them around in the
pre-defined area and the x/y coordinates will get updated
dynamically. Likewise, when entering a new position directly
into the input field, the new position in the scratchboard
changes after your cursor leaves the input field.
You have to click on the 'OK'-button below the tables to save
the new positions. If you want to place a new element, first
add it to the table of elements and then you can drag the new
element around.
By changing the paper size and the orientation you can change
the size of the scratchboard as well. You can do so by just
changing the dropdown field below, and the scratchboard will
resize automatically, without interfering with the current
placement of the elements.
If ever an element gets out of range you can either enlarge the
paper size or click on the 'reset' button to place all elements
below each other.
NOTE: You have to use a recent browser like IE6 or Mozilla to
get this control to work. The basic Drag&Drop script
functionality was kindly borrowed from www.youngpup.net and is
underlying so specific license.
$cfg['NaturalOrder'] boolean
Sorts database and table names according to natural order (for
example, t1, t2, t10). Currently implemented in the left panel
(Light mode) and in Database view, for the table list.
$cfg['ShowHttpHostTitle'] boolean
Shows the HTTP host name in window's title bar.
$cfg['SetHttpHostTitle'] string
If $cfg['ShowHttpHostTitle'] is TRUE, it shows the real HTTP
host name, unless an alternate name is set here.
$cfg['ErrorIconic'] boolean
Uses icons for warnings, errors and informations.
$cfg['MainPageIconic'] boolean
Uses icons on main page in lists, on right panel top menu and
menu tabs.
$cfg['ReplaceHelpImg'] boolean
Shows a help button instead of the "Documentation" message.
$cfg['ThemePath'] string
If theme manager is active, use this as the path of the
subdirectory containing all the themes.
$cfg['ThemeManager'] boolean
Enables user-selectable themes. See FAQ 2.7.
$cfg['ThemeDefault'] string
The default theme (a subdirectory under cfg['ThemePath']).
$cfg['DefaultQueryTable'] string
$cfg['DefaultQueryDatabase'] string
Default queries that will be displayed in query boxes when user
didn't specify any. Use %d for database name, %t for table name
and %f for a comma separated list of field names. Note that %t
and %f are only applicable to $cfg['DefaultQueryTable'].
$cfg['SQP']['fmtType'] string [html|none]
The main use of the new SQL Parser is to pretty-print SQL
queries. By default we use HTML to format the query, but you
can disable this by setting this variable to 'none'.
$cfg['SQP']['fmtInd'] float
$cfg['SQP']['fmtIndUnit'] string [em|px|pt|ex]
For the pretty-printing of SQL queries, under some cases the
part of a query inside a bracket is indented. By changing
$cfg['SQP']['fmtInd'] you can change the amount of this indent.
Related in purpose is $cfg['SQP']['fmtIndUnit'] which specifies
the units of the indent amount that you specified. This is used
via stylesheets.
$cfg['SQP']['fmtColor'] array of string tuples
This array is used to define the colours for each type of
element of the pretty-printed SQL queries. The tuple format is
class => [HTML colour code | empty string]
If you specify an empty string for the color of a class, it is
ignored in creating the stylesheet. You should not alter the
class names, only the colour strings.
Class name key:
+ comment Applies to all comment sub-classes
+ comment_mysql Comments as "#...\n"
+ comment_ansi Comments as "-- ...\n"
+ comment_c Comments as "/*...*/"
+ digit Applies to all digit sub-classes
+ digit_hex Hexadecimal numbers
+ digit_integer Integer numbers
+ digit_float Floating point numbers
+ punct Applies to all punctuation sub-classes

database/table/column attribute
+ alpha_functionName Identifiers matching a MySQL function name
+ alpha_reservedWord Identifiers matching any other reserved
word
+ alpha_variable Identifiers matching a SQL variable "@foo"
+ alpha_identifier All other identifiers
+ quote Applies to all quotation mark classes
+ quote_double Double quotes "
+ quote_single Single quotes '
+ quote_backtick Backtick quotes `
$cfg['SQLValidator']['use'] boolean
phpMyAdmin now supports use of the Mimer SQL Validator service,
as originally published on Slashdot.
For help in setting up your system to use the service, see the
FAQ #6.14.
$cfg['SQLValidator']['username'] string
$cfg['SQLValidator']['password'] string
The SOAP service allows you to login with anonymous and any
password, so we use those by default. Instead, if you have an
account with them, you can put your login details here, and it
will be used in place of the anonymous login.
$cfg['DBG']['enable'] boolean
DEVELOPERS ONLY!
Enable the DBG extension for debugging phpMyAdmin. Required for
profiling the code.
For help in setting up your system to this, see the Developers
section.
$cfg['DBG']['profile']['enable'] boolean
DEVELOPERS ONLY!
Enable profiling support for phpMyAdmin. This will append a
chunk of data to the end of every page displayed in the main
window with profiling statistics for that page.
You may need to increase the maximum execution time for this to
complete successfully.
$cfg['DBG']['profile']['threshold'] float (units in milliseconds)
DEVELOPERS ONLY!
When profiling data is displayed, this variable controls the
threshold of display for any profiling data, based on the
average time each time has taken. If it is over the threshold
it is displayed, otherwise it is not displayed. This takes a
value in milliseconds. In most cases you don't need to edit
this.
$cfg['ColumnTypes'] array
All possible types of a MySQL column. In most cases you don't
need to edit this.
$cfg['AttributeTypes'] array

need to edit this.
$cfg['RestrictColumnTypes'] array
Mapping of column types to meta types used for preferring
displayed functions. In most cases you don't need to edit this.
$cfg['RestrictFunctions'] array
Functions preferred for column meta types as defined in
$cfg['RestrictColumnTypes']. In most cases you don't need to
edit this.
$cfg['DefaultFunctions'] array
Functions selected by default when insering/changing row,
Functions are defined for meta types from
$cfg['RestrictColumnTypes'] and for first_timestamp, which is
used for first timestamp column in table.
$cfg['NumOperators'] array
Operators available for search operations on numeric and date
fields.
$cfg['TextOperators'] array
Operators available for search operations on character fields.
Note that we put LIKE by default instead of LIKE %...%, to
avoid unintended performance problems in case of huge tables.
$cfg['EnumOperators'] array
Operators available for search operations on enum fields.
$cfg['NullOperators'] array
Additionnal operators available for search operations when the
field can be null.
Transformations
Introduction - Usage - File structure
[1. Introduction]
To enable transformations, you have to setup the column_info table and
the proper directives. Please see the Configuration section on how to
do so.
You can apply different transformations to the contents of each field.
The transformation will take the content of each field and transform
it with certain rules defined in the selected transformation.
Say you have a field 'filename' which contains a filename. Normally
you would see in phpMyAdmin only this filename. Using transformations
you can transform that filename into a HTML link, so you can click
inside of the phpMyAdmin structure on the field's link and will see
the file displayed in a new browser window. Using transformation
options you can also specify strings to append/prepend to a string or
the format you want the output stored in.
For a general overview of all available transformations and their
options, you can consult your
<www.your-host.com>/<your-install-dir>/libraries/transformations/overv
iew.php installation.
For a tutorial on how to effectively use transformations, see our Link
section on the official phpMyAdmin-homepage.
[2. Usage]
Go to your tbl_properties.inc.php page (i.e. reached through clicking
on the 'properties' link for a table). There click on "Change" (or
change icon) and there you will see three new fields at the end of the
line. They are called 'MIME-type', 'Browser transformation' and
'Transformation options'.
* The field 'MIME-type' is a dropdown field. You have the options to
leave that field empty or to use 'auto' [this feature is not yet
available]. Please note that transformations are inactive as long
as no MIME-type is selected.
* The field 'Browser transformation' is a drop-down field. You can
choose from a hopefully growing amount of pre-defined
transformations. See below for information on how to build your
own transformation.
There are global transformations and mimetype-bound
transformations. Global transformations can be used for any
mimetype. They will take the mimetype, if necessary, into regard.
Mimetype-bound transformations usually only operate on a certain
mimetype. There are transformations which operate on the main
mimetype (like 'image'), which will most likely take the subtype
into regard, and those who only operate on a specific subtype
(like 'image/jpeg').
You can use transformations on mimetypes for which the function
was not defined for. There is no security check for you selected
the right transformation, so take care of what the output will be
like.
* The field 'Transformation options' is a free-type textfield. You
have to enter transform-function specific options here. Usually
the transforms can operate with default options, but it is
generally a good idea to look up the overview to see which options
are necessary.
Much like the ENUM/SET-Fields, you have to split up several
options using the format 'a','b','c',...(NOTE THE MISSING BLANKS).
This is because internally the options will be parsed as an array,
leaving the first value the first element in the array, and so
forth.
If you want to specify a MIME character set you can define it in
the transformation_options. You have to put that outside of the
pre-defined options of the specific mime-transform, as the last
value of the set. Use the format "'; charset=XXX'". If you use a
transform, for which you can specify 2 options and you want to
append a character set, enter "'first parameter','second
parameter','charset=us-ascii'". You can, however use the defaults
for the parameters: "'','','charset=us-ascii'".
[3. File structure]
All mimetypes and their transformations are defined through single
files in the directory 'libraries/transformations/'.
They are stored in files to ease up customization and easy adding of
new transformations.
Because the user cannot enter own mimetypes, it is kept sure that
transformations always work. It makes no sense to apply a
transformation to a mimetype, the transform-function doesn't know to
handle.
One can, however, use empty mime-types and global transformations
which should work for many mimetypes. You can also use transforms on a
different mimetype they where built for, but pay attention to option
usage as well as what the transformation does to your field.
There is a basic file called 'global.inc.php'. This function can be
included by any other transform function and provides some basic
functions.
There are 5 possible file names:
1. A mimetype+subtype transform:
[mimetype]_[subtype]__[transform].inc.php
Please not that mimetype and subtype are separated via '_', which
shall not be contained in their names. The transform
function/filename may contain only characters which cause no
problems in the file system as well as the PHP function naming
convention.
The transform function will the be called
'PMA_transform_[mimetype]_[subtype]__[transform]()'.
Example:
text_html__formatted.inc.php
PMA_transform_text_html__formatted()
2. A mimetype (w/o subtype) transform:
[mimetype]__[transform].inc.php
Please note that there are no single '_' characters. The transform
function/filename may contain only characters which cause no
problems in the file system as well as the PHP function naming
convention.
The transform function will the be called
'PMA_transform_[mimetype]__[transform]()'.
Example:
text__formatted.inc.php
PMA_transform_text__formatted()
3. A mimetype+subtype without specific transform function
[mimetype]_[subtype].inc.php
Please note that there are no '__' characters in the filename. Do
not use special characters in the filename causing problems with
the file system.
No transformation function is defined in the file itself.
Example:
text_plain.inc.php
(No function)
4. A mimetype (w/o subtype) without specific transform function
[mimetype].inc.php
Please note that there are no '_' characters in the filename. Do
not use special characters in the filename causing problems with
the file system.
No transformation function is defined in the file itself.
Example:
text.inc.php
(No function)
5. A global transform function with no specific mimetype
global__[transform].inc.php
The transform function will the be called
'PMA_transform_global__[transform]()'.
Example:
global__formatted
PMA_transform_global__formatted()
So generally use '_' to split up mimetype and subtype, and '__' to
provide a transform function.
All filenames containing no '__' in themselves are not shown as valid
transform functions in the dropdown.
Please see the libraries/transformations/TEMPLATE file for adding your
own transform function. See the
libraries/transformations/TEMPLATE_MIMETYPE for adding a mimetype
without a transform function. Also note the introduction of a function
description in the language files. For each function a
$strTransformation_[filename without .inc.php] has to exist.
You can use the template generator to generate new functions and
entries in the language file.
To create a new transform function please see
libraries/transformations/template_generator.sh. To create a new,
empty mimetype please see
libraries/transformations/template_generator_mimetype.sh.
A transform function always gets passed three variables:
1. $buffer - Contains the text inside of the column. This is the
text, you want to transform.
2. $options - Contains any user-passed options to a transform
function as an array.
3. $meta - Contains an object with field information to your column.
The data is drawn from the output of the mysql_fetch_field()
function. This means, all object properties described on the
manual page are available in this variable and can be used to
transform a field accordingly to unsigned/zerofill/not_null/...
properties.
The $meta->mimetype variable contains the original MIME-type of
the field (i.e. 'text/plain', 'image/jpeg' etc.)

Please have a look at our Link section on the official phpMyAdmin
homepage for in-depth coverage of phpMyAdmin's features and/or
interface.
[1. Server]
[1.1] I'm running PHP 4+ and my server is crashing each time a specific
action is required or phpMyAdmin sends a blank page or a page full of
cryptic characters to my browser, what can I do?
There are some known PHP bugs with output buffering and compression.
Try to set the $cfg['OBGzip'] directive to FALSE in your
config.inc.php file and the zlib.output_compression directive to Off
in your php configuration file.
Furthermore, we know about such problems connected to the release
candidates of PHP 4.2.0 (tested with PHP 4.2.0 RC1 to RC4) together
with MS Internet Explorer. Please upgrade to the release version PHP
4.2.0.
[1.2] My Apache server crashes when using phpMyAdmin.
You should first try the latest versions of Apache (and possibly
MySQL).
See also the other FAQ entry about PHP bugs with output buffering.
If your server keeps crashing, please ask for help in the various
Apache support groups.
[1.3] I'm running phpMyAdmin with "cookie" authentication mode under PHP
4.2.0 or 4.2.1 loaded as an Apache 2+ module but can't enter the script:
I'm always displayed the login screen.
This is a known PHP bug (see this bug report) from the official PHP
bug database. It means there is and won't be any phpMyAdmin fix
against it because there is no way to code a fix.
[1.4] Using phpMyAdmin on IIS, I'm displayed the error message: "The
specified CGI application misbehaved by not returning a complete set of
HTTP headers...".
You just forgot to read the install.txt file from the php
distribution. Have a look at the last message in this bug report from
the official PHP bug database.
[1.5] Using phpMyAdmin on IIS, I'm facing crashes and/or many error
messages with the HTTP or advanced authentication mode.
This is a known problem with the PHP ISAPI filter: it's not so stable.
For some more information and complete testings see the messages
posted by André B. aka "djdeluxe76" in this thread from the phpWizard
forum.
Please use instead the cookie authentication mode.
[1.6] I can't use phpMyAdmin on PWS: nothing is displayed!
This seems to be a PWS bug. Filippo Simoncini found a workaround (at
this time there is no better fix): remove or comment the DOCTYPE
declarations (2 lines) from the scripts header.inc.php,
header_printview.inc.php, index.php, left.php and
libraries/common.lib.php.
[1.7] How can I GZip or Bzip a dump or a CSV export. It does not seem to
work.
These features are based on the gzencode() and bzcompress() PHP
functions to be more independent of the platform (Unix/Windows, Safe
Mode or not, and so on). So, you must have PHP4 >= 4.0.4 and
Zlib/Bzip2 support (--with-zlib and --with-bz2).
We faced PHP crashes when trying to download a dump with MS Internet
Explorer when phpMyAdmin is run with a release candidate of PHP 4.2.0.
In this case you should switch to the release version of PHP 4.2.0.
[1.8] I cannot insert a text file in a table, and I get an error about safe
mode being in effect.
Your uploaded file is saved by PHP in the "upload dir", as defined in
php.ini by the variable upload_tmp_dir (usually the system default is
/tmp).
We recommend the following setup for Apache servers running in safe
mode, to enable uploads of files while being reasonably secure:
* create a separate directory for uploads: mkdir /tmp/php
* give ownership to the Apache server's user.group: chown
apache.apache /tmp/php
* give proper permission: chmod 600 /tmp/php
* put upload_tmp_dir = /tmp/php in php.ini
* restart Apache
[1.9] I'm having troubles when uploading files. In general file uploads
don't work on my system and uploaded files have a Content-Type: header in
the first line.
It's not really phpMyAdmin related but RedHat 7.0. You have a RedHat
7.0 and you updated your PHP RPM to php-4.0.4pl1-3.i386.rpm, didn't
you?
So the problem is that this package has a serious bug that was
corrected ages ago in PHP (2001-01-28: see PHP's bug tracking system
for more details). The problem is that the bugged package is still
available though it was corrected (see RedHat's BugZilla for more
details).
So please download the fixed package (4.0.4pl1-9) and the problem
should go away.
And that fixes the \r\n problem with file uploads!
[1.10] I'm having troubles when uploading files with phpMyAdmin running on
a secure server. My browser is Internet Explorer and I'm using the Apache
server.
As suggested by "Rob M" in the phpWizard forum, add this line to your
httpd.conf:
SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown
It seems to clear up many problems between Internet Explorer and SSL.
[1.11] I get an 'open_basedir restriction' while uploading a file from the
query box.
Since version 2.2.4, phpMyAdmin supports servers with open_basedir
restrictions. Assuming that the restriction allows you to open files
in the current directory ('.'), all you have to do is create a 'tmp'
directory under the phpMyAdmin install directory, with permissions 777
and the same owner as the owner of your phpMyAdmin directory. The
uploaded files will be moved there, and after execution of your SQL
commands, removed.
[1.12] I have lost my MySQL root password, what can I do?
The MySQL manual explains how to reset the permissions.
[1.13] I get an error 'No SQL query' when trying to execute a bookmark.
If PHP does not have read/write access to its upload_tmp_dir, it
cannot access the uploaded query.
[1.14] I get an error 'No SQL query' when trying to submit a query from the
convenient text area.
Check the post_max_size directive from your PHP configuration file and
try to increase it.
[1.15] I have problems with mysql.user field names.
In older MySQL versions, the User and Password fields were named user
and password. Please modify your field names to align with current
standards.
[1.16] I cannot upload big dump files (memory, http or timeout problems).
The first things to check (or ask your host provider to check) are the
values of upload_max_filesize, memory_limit and post_max_size in the
php.ini configuration file.
All of these three settings limit the maximum size of data that can be
submitted and handled by PHP. One user also said that post_max_size
and memory_limit need to be larger than upload_max_filesize.
If you get a timeout problem, look at the $cfg['UploadDir'] feature.
[1.17] Which MySQL versions does phpMyAdmin support?
All MySQL versions from 3.23.32 till 5.0 (except for 4.1.0 and 4.1.1)
are fully supported. Please note that the older your MySQL version is,
the more limitations you will have to face.
phpMyAdmin may connect to your MySQL server using php's classic MySQL
extension as well as the improved MySQL extension (MySQLi) that is
available in php 5.0.
Either way, the developers of both extensions recommend to use the
classic extension for MySQL 4.0 and below and MySQLi for MySQL 4.1 and
newer.
When compiling php, we strongly recommend that you manually link the
MySQL extension of your choice to a MySQL client library of at least
the same minor version since the one that is bundled with some php
distributions is rather old and might cause problems (see also FAQ
1.17a).
MySQL 5.1 is not yet supported.
[1.17a] I cannot connect to the MySQL server. It alaways returns the error
message, "Client does not support authentication protocol requested by
server; consider upgrading MySQL client"
You tried to access MySQL with an old MySQL client library. The
version of your MySQL client library can be checked in your phpinfo()
output.
In general, it should have at least the same minor version as your
server - as mentioned in FAQ 1.17.
The only way to fix this problem is manually compiling php and its
MySQL extension against a current MySQL client library.
If you still face this problem, please compile your MySQL client
library against the same or a newer MySQL release.
[1.18] I'm running MySQL <= 4.0.1 having lower_case_table_names set to 1.
If I create a new table with a capital letter in its name it is changed to
lowercase as it should. But if I try to DROP this table MySQL is unable to
find the corresponding file.
This is a bug of MySQL <= 4.0.1. Please upgrade to at least
MySQL 4.0.2 or turn off your lower_case_table_names directive.
[1.19] I can't run the "display relations" feature because the script seems
not to know the font face I'm using!
The "FPDF" library we're using for this feature requires some special
files to use font faces.
Please refers to the FPDF manual to build these files.
[1.20] I receive the error "cannot load MySQL extension, please check PHP
Configuration".
To connect to a MySQL server, PHP needs a set of MySQL functions
called "MySQL extension". This extension may be part of the PHP
distribution (compiled-in), otherwise it needs to be loaded
dynamically. Its name is probably mysql.so or php_mysql.dll.
phpMyAdmin tried to load the extension but failed.
Usually, the problem is solved by installing a software package called
"PHP-MySQL" or something similar.
[1.21] I am running the CGI version of PHP under Unix, and I cannot login
using cookie auth.
In php.ini, set mysql.max_links higher than 1.
[1.22] I don't see the "Location of text file" field, so I cannot upload.
This is most likely because in php.ini, your file_uploads parameter is
not set to "on".
[1.23] I'm running MySQL on a Win32 machine. Each time I create a new table
the table and field names are changed to lowercase!
This happens because the MySQL directive lower_case_table_names
defaults to 1 (ON) in the Win32 version of MySQL. You can change this
behavior by simply changing the directive to 0 (OFF):
Just edit your my.ini file that should be located in your Windows
directory and add the following line to the group [mysqld]:
set-variable = lower_case_table_names=0
Next, save the file and restart the MySQL service. You can always
check the value of this directive using the query
SHOW VARIABLES LIKE 'lower_case_table_names';
[1.24] Some characters are being truncated in my queries, or I get
characters randomly added. I am running PHP 4.2.3.
This is a PHP 4.2.3 bug.
[1.25] I am running Apache with mod_gzip-1.3.26.1a on Windows XP, and I get
problems, such as undefined variables when I run a SQL query.
A tip from Jose Fandos: put a comment on the following two lines in
httpd.conf, like this:
# mod_gzip_item_include file \.php$
# mod_gzip_item_include mime "application/x-httpd-php.*"
as this version of mod_gzip on Apache (Windows) has problems handling
PHP scripts. Of course you have to restart Apache.
[1.26] I just installed phpMyAdmin in my document root of IIS but I get the
error "No input file specified" when trying to run phpMyAdmin.
This is a permission problem. Right-click on the phpmyadmin folder and
choose properties. Under the tab Security, click on "Add" and select
the user "IUSR_machine" from the list. Now set his permissions and it
should work.
[1.27] I get empty page when I want to view huge page (eg.
db_details_structure.php with plenty of tables).
This is a PHP bug that occur when GZIP output buffering is enabled. If
you turn off it (by $cfg['OBGzip'] = FALSE in config.inc.php), it
should work. This bug will be fixed in PHP 5.0.0.
[1.28] My MySQL server sometimes refuses queries and returns the message
'Errorcode: 13'. What does this mean?
This can happen due to a MySQL bug when having database / table names
with upper case characters although lower_case_table_names is set to
1. To fix this, turn off this directive, convert all database and
table names to lower case and turn it on again. Alternatively, there's
a bug-fix available starting with MySQL 3.23.56 / 4.0.11-gamma.
[1.29] When I create a table or modify a field, I get an error and the
fields are duplicated.
It is possible to configure Apache in such a way that PHP has problems
interpreting .php files.
The problems occur when two different (and conflicting) set of
directives are used:
SetOutputFilter PHP
SetInputFilter PHP
&
AddType application/x-httpd-php .php
In the case we saw, one set of directives was in
/etc/httpd/conf/httpd.conf, while the other set was in
/etc/httpd/conf/addon-modules/php.conf.
The recommended way is with AddType, so just comment out the first set
of lines and restart Apache:
#SetOutputFilter PHP
#SetInputFilter PHP
[1.30] I get the error "left.php: Missing hash".
This problem is known to happen when the server is running Turck
MMCache but upgrading MMCache to version 2.3.21 solves the problem.
[1.31] Does phpMyAdmin support php5?
Yes.
However, phpMyAdmin needs to be backwards compatible to php4. This is
why you won't be able to run phpMyAdmin having enabled E_STRICT in
your error_reporting settings.
[2. Configuration]
[2.1] The error message "Warning: Cannot add header information - headers
already sent by ..." is displayed, what's the problem?
Edit your config.inc.php or .php file and ensure there is nothing
(I.E. no blank lines, no spaces, no characters...) neither before the
<?php tag at the beginning, neither after the ?> tag at the end.
[2.2] phpMyAdmin can't connect to MySQL. What's wrong?
Either there is an error with your PHP setup or your username/password
is wrong. Try to make a small script which uses mysql_connect and see
if it works. If it doesn't, it may be you haven't even compiled MySQL
support into PHP.
[2.3] The error message "Warning: MySQL Connection Failed: Can't connect to
local MySQL server through socket '/tmp/mysql.sock' (111)..." is displayed.
What can I do?
For RedHat users, Harald Legner suggests this on the mailing list:
On my RedHat-Box the socket of MySQL is /var/lib/mysql/mysql.sock. In
your php.ini you will find a line
mysql.default_socket = /tmp/mysql.sock
change it to
mysql.default_socket = /var/lib/mysql/mysql.sock
Then restart apache and it will work.
Here is a fix suggested by Brad Ummer in the phpwizard forum:
* First, you need to determine what socket is being used by MySQL.
To do this, telnet to your server and go to the MySQL bin
directory. In this directory there should be a file named
mysqladmin. Type ./mysqladmin variables, and this should give you
a bunch of info about your MySQL server, including the socket
(/tmp/mysql.sock, for example).
* Then, you need to tell PHP to use this socket.
Assuming you are using PHP 3.0.10 or better, you can specify the
socket to use when you open the connection. To do this in
phpMyAdmin, you need to complete the socket information in the
config.inc.php.
For example: $cfg['Servers'][$i]['socket'] = '/tmp/mysql.sock';
Please also make sure that the permissions of this file allow to
be readable by your webserver (i.e. '0755').
Have also a look at the corresponding section of the MySQL
documentation.
[2.4] Nothing is displayed by my browser when I try to run phpMyAdmin, what
can I do?
Try to set the $cfg['OBGZip'] directive to FALSE in the phpMyAdmin
configuration file. It helps sometime.
Also have a look at your PHP version number: if it contains "4.0b..."
it means you're running a beta version of PHP. That's not a so good
idea, please upgrade to a plain revision.
[2.5] Each time I want to insert or change a record or drop a database or a
table, an error 404 (page not found) is displayed or, with HTTP or cookie
authentication, I'm asked to login again. What's wrong?
Check the value you set for the $cfg['PmaAbsoluteUri'] directive in
the phpMyAdmin configuration file.
[2.6] I get an "Access denied for user: 'root@localhost' (Using password:
YES)"-error when trying to access a MySQL-Server on a host which is
port-forwarded for my localhost.
When you are using a port on your localhost, which you redirect via
port-forwarding to another host, MySQL is not resolving the localhost
as expected.
Erik Wasser explains: The solution is: if your host is "localhost"
MySQL (the commandline tool 'mysql' as well) always tries to use the
socket connection for speeding up things. And that doesn't work in
this configuration with port forwarding.
If you enter "127.0.0.1" as hostname, everything is right and MySQL
uses the TCP connection.
[2.7] Using and creating themes
Themes are configured with $cfg['ThemePath'], $cfg['ThemeManager'] and
$cfg['ThemeDefault'].
Under $cfg['ThemePath'], you should not delete the directory
"original" or its underlying structure, because this is the system
theme used by phpMyAdmin. "original" contains all images and styles,
for backwards compatibility and for all themes that would not include
images or css-files.
If $cfg['ThemeManager'] is enabled, you can select your favorite theme
on the main page. Your selected theme will be stored in a cookie.
To create a theme:
* make a new subdirectory (for example "your_theme_name") under
$cfg['ThemePath'] (by default themes)
* copy the files and directories from "original" to
"your_theme_name"
* edit the css-files in "your_theme_name/css"
* put your new images in "your_theme_name/img"
* edit layout.inc.php in "your_theme_name"
* edit info.inc.php in "your_theme_name" to contain your chosen
theme name, that will be visible in user interface
* make a new screenshot of your theme and save it under
"your_theme_name/screen.png"
In theme directory there is file info.inc.php which contains theme
verbose name, theme generation and theme version. These versions and
generations are enumerated from 1 and do not have any direct
dependance on phpMyAdmin version. Themes within same generation should
be bacward compatible - theme with version 2 should work in phpMyAdmin
requiring version 1. Themes with different generation are
incompatible.
If you do not want to use your own symbols and buttons, remove the
directory "img" in "your_theme_name". phpMyAdmin will use the default
icons and buttons (from the system-theme "original").
[3. Known limitations]
[3.1] When using HTTP authentication, an user who logged out can not
relogin in with the same nick.
This is related to the authentication mechanism (protocol) used by
phpMyAdmin. To bypass this problem: just close all the opened browser
windows and then go back to phpMyAdmin. You should be able to log in
again.
[3.2] When dumping a large table in compressed mode, I get a memory limit
error or a time limit error.
Compressed dumps are built in memory and because of this are limited
to php's memory limit. For GZip/BZip2 exports this can be overcome
since 2.5.4 using $cfg['CompressOnFly'] (enabled by default). Zip
exports can not be handled this way, so if you need Zip files for
larger dump, you have to use another way.
[3.3] With InnoDB tables, I lose foreign key relationships when I rename or
alter a table.
This seems to be a InnoDB bug (fixed in MySQL 3.23.50?).
[3.4] I am unable to import dumps I created with the mysqldump tool bundled
with the MySQL server distribution.
The problem is that mysqldump creates invalid comments like this:
-- MySQL dump 8.22
--
-- Host: localhost Database: database
---------------------------------------------------------
-- Server version 3.23.54
The invalid part of the code is the horizontal line made of dashes
that appears once in every dump created with mysqldump. If you want to
run your dump you have to turn it into valid MySQL. This means, you
have to add a whitespace after the first two dashes of the line or add
a # before it:
-- -------------------------------------------------------
or
#---------------------------------------------------------
[3.5] When using nested folders ($cfg['LeftFrameTableSeparator']) there are
some multiple hierarchies displayed in a wrong manner?!
Please note that you should not use the separating string multiple
times without any characters between them, or at the beginning/end of
your table name. If you have to, think about using another
TableSeparator or disabling that feature
[3.6] What is currently not supported in phpMyAdmin about InnoDB?
In Relation view, being able to choose a table in another database, or
having more than one index field in the foreign key.
In Query-by-example (Query), automatic generation of the query LEFT
JOIN from the foreign table.
In PDF schema editing, automatic layout.
[3.7] I have table with many (100+) fields and when I try to browse table I
get series of errors like "Warning: unable to parse url". How can this be
fixed?
Your table neither have a primary key nor an unique one, so we must
use a long expression to identify this row. This causes problems to
parse_url function. The workaround is to create a primary or unique
key.
[3.8] I cannot use (clickable) HTML-forms in fields where I put a
MIME-Transformation onto!
Due to a surrounding form-container (for multi-row delete checkboxes),
no nested forms can be put inside the table where phpMyAdmin displays
the results. You can, however, use any form inside of a table if keep
the parent form-container with the target to tbl_row_delete.php and
just put your own input-elements inside. If you use a custom submit
input field, the form will submit itself to the displaying page again,
where you can validate the $HTTP_POST_VARS in a transformation. For a
tutorial on how to effectively use transformations, see our Link
section on the official phpMyAdmin-homepage.
[3.9] I get error messages when using "--sql_mode=ANSI" for the MySQL
server
When MySQL is running in ANSI-compatibility mode, there are some major
differences in how SQL is structured (see
http://dev.mysql.com/doc/mysql/en/ANSI_mode.html). Most important of
all, the quote-character (") is interpreted as an identifier quote
character and not as a string quote character, which makes many
internal phpMyAdmin operations into invalid SQL statements. There is
no workaround to this behaviour. News to this item will be posted in
Bug report #816858
[3.10] Homonyms and no primary key: When the results of a SELECT display
more that one column with the same value (for example SELECT lastname from
employees where firstname like 'A%' and two "Smith" values are displayed),
if I click Edit I cannot be sure that I am editing the intended row.
Please make sure that your table has a primary key, so that phpMyAdmin
can use it for the Edit and Delete links.
[4. ISPs, multi-user installations ]
[4.1] I'm an ISP. Can I setup one central copy of phpMyAdmin or do I need
to install it for each customer.
Since version 2.0.3, you can setup a central copy of phpMyAdmin for
all your users. The development of this feature was kindly sponsored
by NetCologne GmbH. This requires a properly setup MySQL user
management and phpMyAdmin HTTP or cookie authentication. See the
install section on "Using HTTP authentication".
[4.2] What's the preferred way of making phpMyAdmin secure against evil
access.
This depends on your system.
If you're running a server which cannot be accessed by other people,
it's sufficient to use the directory protection bundled with your
webserver (with Apache you can use .htaccess files, for example).
If other people have telnet access to your server, you should use
phpMyAdmin's HTTP authentication feature.
Suggestions:
* Your config.inc.php file should be chmod 660.
* All your phpMyAdmin files should be chown -R phpmy.apache, where
phpmy is a user whose password is only known to you, and apache is
the group under which Apache runs.
* You should use PHP safe mode, to protect from other users that try
to include your config.inc.php in their scripts.
[4.3] I get errors about not being able to include a file in /lang or in
/libraries.
Check php.ini, or ask your sysadmin to check it. The include_path must
contain "." somewhere in it, and open_basedir, if used, must contain
"." and "./lang" to allow normal operation of phpMyAdmin.
[4.4] phpMyAdmin always gives "Access denied" when using HTTP
authentication.
This could happen for several reasons:
* $cfg['Servers'][$i]['controluser'] and/or
$cfg['Servers'][$i]['controlpass'] are wrong.
* The username/password you specify in the login-dialog are invalid.
* You have already setup a security mechanism for the
phpMyAdmin-directory, eg. a .htaccess file. This would interfere
with phpMyAdmin's authentication, so remove it.
[4.5] Is it possible to let users create their own databases?
Starting with 2.2.5, in the user management page, you can enter a
wildcard database name for a user (for example "joe%"), and put the
privileges you want. For example, adding SELECT, INSERT, UPDATE,
DELETE, CREATE, DROP, INDEX, ALTER would let a user create/manage
his/her database(s).
[4.6] How can I use the Host-based authentication additions?
If you have existing rules from an old .htaccess file, you can take
them and add a username between the 'deny'/'allow' and 'from' strings.
Using the username wildcard of '%' would be a major benefit here if
your installation is suited to using it. Then you can just add those
updated lines into the $cfg['Servers'][$i]['AllowDeny']['rules']
array.
If you want a pre-made sample, you can try this fragment. It stops the
'root' user from logging in from any networks other than the private
network IP blocks.
//block root from logging in except from the private networks
$cfg['Servers'][$i]['AllowDeny']['order'] = 'deny,allow';
$cfg['Servers'][$i]['AllowDeny']['rules'] = array(
'deny root from all',
'allow root from localhost',
'allow root from 10.0.0.0/8',
'allow root from 192.168.0.0/16',
'allow root from 172.16.0.0/12',
);
[4.7] Authentication window is displayed more than once, why?
This happens if you are using a URL to start phpMyAdmin which is
different than the one set in your $cfg['PmaAbsoluteUri']. For
example, a missing "www", or entering with an IP address while a
domain name is defined in the config file.
[5. Browsers or client OS]
[5.1] I get an out of memory error, and my controls are non-functional,
when trying to create a table with more than 14 fields.
We could reproduce this problem only under Win98/98SE. Testing under
WinNT4 or Win2K, we could easily create more than 60 fields.
A workaround is to create a smaller number of fields, then come back
to your table properties and add the other fields.
[5.2] With Xitami 2.5b4, phpMyAdmin won't process form fields.
This is not a phpMyAdmin problem but a Xitami known bug: you'll face
it with each script/website that use forms.
Upgrade or downgrade your Xitami server.
[5.3] I have problems dumping tables with Konqueror (phpMyAdmin 2.2.2).
With Konqueror 2.1.1: plain dumps, zip and GZip dumps work ok, except
that the proposed file name for the dump is always 'tbl_dump.php'.
Bzip2 dumps don't seem to work.
With Konqueror 2.2.1: plain dumps work; zip dumps are placed into the
user's temporary directory, so they must be moved before closing
Konqueror, or else they disappear. GZip dumps give an error message.
Testing needs to be done for Konqueror 2.2.2.
[5.4] I can't use the cookie authentication mode because Internet Explorer
never stores the cookies.
MS Internet Explorer seems to be really buggy about cookies, at least
till version 6. And thanks to Andrew Zivolup we've traced also a PHP
4.1.1 bug in this area!
Then, if you're running PHP 4.1.1, try to upgrade or downgrade... it
may work!
[5.5] In Internet Explorer 5.0, I get JavaScript errors when browsing my
rows.
Upgrade to at least Internet Explorer 5.5 SP2.
[5.6] In Internet Explorer 5.0, 5.5 or 6.0, I get an error (like "Page not
found") when trying to modify a row in a table with many fields, or with a
text field
Your table neither have a primary key nor an unique one, so we must
use a long URL to identify this row. There is a limit on the length of
the URL in those browsers, and this not happen in Netscape, for
example. The workaround is to create a primary or unique key, or use
another browser.
[5.7] I refresh (reload) my browser, and come back to the welcome page.
Some browsers support right-clicking into the frame you want to
refresh, just do this in the right frame.
[5.8] With Mozilla 0.9.7 I have problems sending a query modified in the
query box.
Looks like a Mozilla bug: 0.9.6 was OK. We will keep an eye on future
Mozilla versions.
[5.9] With Mozilla 0.9.? to 1.0 and Netscape 7.0-PR1 I can't type a
whitespace in the SQL-Query edit area: the page scrolls down.
This is a Mozilla bug (see bug #26882 at BugZilla).
[5.10] With Netscape 4.75 I get empty rows between each row of data in a
CSV exported file.
This is a known Netscape 4.75 bug: it adds some line feeds when
exporting data in octet-stream mode. Since we can't detect the
specific Netscape version, we cannot workaround this bug.
[5.11] Extended-ASCII characters like German umlauts are displayed wrong.
Please ensure that you have set your browser's character set to the
one of the language file you have selected on phpMyAdmin's start page.
Alternatively, you can try the auto detection mode that is supported
by the recent versions of the most browsers.
[5.12] Apple OS X: Safari browser changes special characters to "?".
This issue has been reported by a OS X user, who adds that Chimera,
Netscape and Mozilla do not have this problem.
[5.13] With Internet Explorer 5.5 or 6, and HTTP authentication type, I
cannot manage two servers: I login to the first one, then the other one,
but if I switch back to the first, I have to login on each operation.
This is a bug in Internet Explorer, other browsers do not behave this
way.
[5.14] Using Opera6, I can manage to get to the authentication, but nothing
happens after that, only a blank screen.
Having $cfg['QueryFrameJS'] set to TRUE, this leads to a bug in
Opera6, because it is not able to interpret frameset definitiions
written by JavaScript. Please upgrade to Opera7 at least.
[5.15] I have display problems with Safari.
Please upgrade to at least version 1.2.3.
[6. Using phpMyAdmin]
[6.1] I can't insert new rows into a table / I can't create a table - MySQL
brings up a SQL-error.
Examine the SQL error with care. Often the problem is caused by
specifying a wrong field-type.
Common errors include:
* Using VARCHAR without a size argument
* Using TEXT or BLOB with a size argument
Also, look at the syntax chapter in the MySQL manual to confirm that
your syntax is correct.
[6.2] When I create a table, I click the Index checkbox for 2 fields and
phpMyAdmin generates only one index with those 2 fields.
In phpMyAdmin 2.2.0 and 2.2.1, this is the way to create a
multi-fields index. If you want two indexes, create the first one when
creating the table, save, then display the table properties and click
the Index link to create the other index.
[6.3] How can I insert a null value into my table?
Since version 2.2.3, you have a checkbox for each field that can be
null. Before 2.2.3, you had to enter "null", without the quotes, as
the field's value. Since version 2.5.5, you have to use the checkbox
to get a real NULL value, so if you enter "NULL" this means you want a
literal NULL in the field, and not a NULL value (this works in PHP4).
[6.4] How can I backup my database or table?
Click on a database or table name in the left frame, the properties
will be displayed. Then on the menu, click "Export", you can dump the
structure, the data, or both. This will generate standard SQL
statements that can be used to recreate your database/table.
You will need to choose "Save as file", so that phpMyAdmin can
transmit the resulting dump to your station. Depending on your PHP
configuration, you will see options to compress the dump. See also the
$cfg['ExecTimeLimit'] configuration variable.
For additional help on this subject, look for the word "dump" in this
document.
[6.5] How can I restore (upload) my database or table using a dump? How can
I run a ".sql" file.
Click on a database name in the left frame, the properties will be
local displayed. Then in the "Run SQL query" section, type in your
dump filename, or use the Browse button. Then click Go.
For additional help on this subject, look for the word "upload" in
this document.
[6.6] How can I use the relation table in Query-by-example?
Here is an example with the tables persons, towns and countries, all
located in the database mydb. If you don't have a pma_relation table,
create it as explained in the configuration section. Then create the
example tables:
CREATE TABLE REL_countries (
country_code char(1) NOT NULL default '',
description varchar(10) NOT NULL default '',
PRIMARY KEY (country_code)
) TYPE=MyISAM;
INSERT INTO REL_countries VALUES ('C', 'Canada');
CREATE TABLE REL_persons (
id tinyint(4) NOT NULL auto_increment,
person_name varchar(32) NOT NULL default '',
town_code varchar(5) default '0',
country_code char(1) NOT NULL default '',
PRIMARY KEY (id)
) TYPE=MyISAM;
INSERT INTO REL_persons VALUES (11, 'Marc', 'S', '');
INSERT INTO REL_persons VALUES (15, 'Paul', 'S', 'C');
CREATE TABLE REL_towns (
town_code varchar(5) NOT NULL default '0',
description varchar(30) NOT NULL default '',
PRIMARY KEY (town_code)
) TYPE=MyISAM;
INSERT INTO REL_towns VALUES ('S', 'Sherbrooke');
INSERT INTO REL_towns VALUES ('M', 'Montréal');
To setup appropriate links and display information:
* on table "REL_persons" click Structure, then Relation view
* in Links, for "town_code" choose "REL_towns->code"
* in Links, for "country_code" choose "REL_countries->country_code"
* on table "REL_towns" click Structure, then Relation view
* in "Choose field to display", choose "description"
* repeat the two previous steps for table "REL_countries"
Then test like this:
* Click on your db name in the left frame
* Choose "Query"
* Use tables: persons, towns, countries
* Click "Update query"
* In the fields row, choose persons.person_name and click the "Show"
tickbox
* Do the same for towns.description and countries.descriptions in
the other 2 columns
* Click "Update query" and you will see in the query box that the
correct joins have been generated
* Click "Submit query"
[6.7] How can I use the "display field" feature?
Starting from the previous example, create the pma_table_info as
explained in the configuration section, then browse your persons
table, and move the mouse over a town code or country code.
See also FAQ 6.21 for an additionnal feature that "display field"
enables: drop-down list of possible values.
[6.8] How can I produce a PDF schema of my database?
First you have to fill the "relation", "table_coords" and "pdf_pages"
configuration variables.
Then, think about your schema layout: which tables will go on which
pages.
* Click on your db name in the left frame
* Choose "Structure" in the navigation on top
* Choose "Edit PDF Pages" which should be somewhere at the bottom of
the page
* Enter the name for a first pdf page and submit (you can also use
the "Automatic layout", which will place on your page all the
tables that are linked)
* Choose this page to edit
* Now add a table you want to show on this page and its coordinates
and submit
First you will have to guess those coordinates of course, so just
expect to have an area of about 297 * 210 and put the tables
coordinates somewhere in there, you will be able to have a look at
what happened and change them later.
For example, x=100 and y=200 means that the table will be at 200
mm down and 100 mm right from the upper left corner.
Actually if you have a width of more than 300 or a height of more
than 200 then it will automatically be scaled but 200*100 is a
good start to have an idea of what coordinates to use.
* There is also a visual editor (scratchboard) available, see the
explanation at the $cfg['WYSIWYG-PDF'] section.
* After every table you submitted you will have the possibility to
submit more tables
* When you have entered enough tables Click on your db name in the
left frame again
* Now, again at the bottom of the page you should be able to choose
"Display PDF schema"
For testing it might be useful to show the grid as well, so you
can see the coordinates used.
Maybe also choose color and submit.
* Save the file he will offer you to something like Schema.pdf
(Internet Explorer has some bug there which might make it offer it
without an extension. Under Windows it is important to have the
extension ".pdf", under other OSes you should be fine just saving
the file under the name it offers).
[6.9] phpMyAdmin is changing the type of one of my columns!
No, it's MySQL that is doing silent column type changing.
[6.10] When creating a privilege, what happens with underscores in the
database name?
If you do not put a backslash before the underscore, this is a
wildcard grant, and the underscore means "any character". So, if the
database name is "john_db", the user would get rights to john1db,
john2db...
If you put a backslash before the underscore, it means that the
database name will have a real underscore.
[6.11] What is the curious symbol ø in the statistics pages?
It means "average".
[6.12] I want to understand some Export options.
"Complete inserts" adds the column names on every INSERT command, for
better documentation (but resulting file is bigger).
"Extended inserts" provides a shorter dump file by using only once the
INSERT verb and the table name.
"Enclose table and field names with backquotes" ensures that field and
table names formed with special characters are protected.
"Add AUTO_INCREMENT value" ensures, that AUTO_INCREMENT value (if any)
will be included in backup.
"Add into comments" includes column comments, relations and MIME types
set in the PMA-DB in the dump as SQL comments (/* xxx */).
[6.13] I would like to create a database with a dot in its name.
This is a bad idea, because in MySQL the syntax "database.table" is
the normal way to reference a database and table name. Worse, MySQL
will usually let you create a database with a dot, but then you cannot
work with it, nor delete it.
[6.14] How do I set up the SQL Validator?
To use it, you need a very recent version of PHP, 4.3.0 recommended,
with XML, PCRE and PEAR support. On your system command line, run
"pear install Net_Socket Net_URL HTTP_Request Mail_Mime Net_DIME SOAP"
to get the necessary PEAR modules for usage.
On a more recent pear version, I had problems with the state of
Net_DIME being beta, so this single command "pear -d
preferred_state=beta install -a SOAP" installed all the needed
modules.
If you use the Validator, you should be aware that any SQL statement
you submit will be stored anonymously (database/table/column names,
strings, numbers replaced with generic values). The Mimer SQL
Validator itself, is © 2001 Upright Database Technology. We utilize it
as free SOAP service.
[6.15] I want to add a BLOB field and put an index on it, but MySQL says
"BLOB column '...' used in key specification without a key length".
The right way to do this, is to create the field without any indexes,
then display the table structure and use the "Create an index" dialog.
On this page, you will be able to choose your BLOB field, and set a
size to the index, which is the condition to create an index on a BLOB
field.
[6.16] How can I simply move in page with plenty editing fields?
You can use Ctrl+arrows for moving on most pages with plenty editing
fields (table structure changes, row editing, etc.) (must be enabled
in configuration - see. $cfg['CtrlArrowsMoving']). You can also have a
look at the directive $cfg['DefaultPropDisplay'] ('vertical') and see
if this eases up editing for you.
[6.17] Transformations: I can't enter my own mimetype! WTF is this feature
then useful for?
Slow down :). Defining mimetypes is of no use, if you can't put
transformations on them. Otherwise you could just put a comment on the
field. Because entering your own mimetype will cause serious syntax
checking issues and validation, this introduces a high-risk
false-user-input situation. Instead you have to initialize mimetypes
using functions or empty mimetype definitions.
Plus, you have a whole overview of available mimetypes. Who knows all
those mimetypes by heart so he/she can enter it at will?
[6.18] Bookmarks: Where can I store bookmarks? Why can't I see any
bookmarks below the query box? What is this variable for?
Any query you have executed can be stored as a bookmark on the page
where the results are displayed. You will find a button labeled
'Bookmark this query' just at the end of the page.
As soon as you have stored a bookmark, it is related to the database
you run the query on. You can now access a bookmark dropdown on each
page, the query box appears on for that database.
Since phpMyAdmin 2.5.0 you are also able to store variables for the
bookmarks. Just use the string /*[VARIABLE]*/ anywhere in your query.
Everything which is put into the value input box on the query box page
will replace the string "/*[VARIABLE]*/" in your stored query. Just be
aware of that you HAVE to create a valid query, otherwise your query
won't be even able to be stored in the database.
Also remember, that everything else inside the /*[VARIABLE]*/ string
for your query will remain the way it is, but will be stripped of the
/**/ chars. So you can use:
/*, [VARIABLE] AS myname */
which will be expanded to
, VARIABLE as myname
in your query, where VARIABLE is the string you entered in the input
box. If an empty string is provided, no replacements are made.
A more complex example. Say you have stored this query:
SELECT Name, Address FROM addresses WHERE 1 /* AND Name LIKE
'%[VARIABLE]%' */
Say, you now enter "phpMyAdmin" as the variable for the stored query,
the full query will be:
SELECT Name, Address FROM addresses WHERE 1 AND Name LIKE
'%phpMyAdmin%'
You can use multiple occurences of /*[VARIABLE]*/ in a single query.
NOTE THE ABSENCE OF SPACES inside the "/**/" construct. Any spaces
inserted there will be later also inserted as spaces in your query and
may lead to unexpected results especially when using the variable
expansion inside of a "LIKE ''" expression.
Your initial query which is going to be stored as a bookmark has to
yield at least one result row so you can store the bookmark. You may
have that to work around using well positioned "/**/" comments.
[6.19] How can I create simple LaTeX document to include exported table?
You can simply include table in your LaTeX documents, minimal sample
document should look like following one (assuming you have table
exported in file table.tex):
\documentclass{article} % or any class you want
\usepackage{longtable} % for displaying table
\begin{document} % start of document
\include{table} % including exported table
\end{document} % end of document
[6.20] In MySQL 4, I see a lot of databases which are not mine, and cannot
access them.
Upgrading to MySQL 4 usually gives users those global privileges:
CREATE TEMPORARY TABLES, SHOW DATABASES, LOCK TABLES. Those privileges
also enables users to see all the database names, until you upgrade
the grant tables as described in the MySQL manual. See this bug
report.
So if your users do not need those privileges, you can remove them and
their databases list will shorten.
[6.21] In edit/insert mode, how can I see a list of possible values for a
field, based on some foreign table?
You have to setup appropriate links between the tables, and also setup
the "display field" in the foreign table. See FAQ 6.6 for an example.
Then, if there are 200 values or less in the foreign table, a
drop-down list of values will be available. You will see two lists of
values, the first list containing the key and the display field, the
second list containing the display field and the key. The reason for
this is to be able to type the first letter of either the key or the
display field.
For 200 values or more, a distinct window will appear, to browse
foreign key values and choose one.
[6.22] Bookmarks: Can I execute a default bookmark automatically when
entering Browse mode for a table?
Yes. If a bookmark has the same label as a table name, it will be
executed.
[6.23] Export: I heard phpMyAdmin can export MS Excel files, how can I
enable that?
You can either export as CSV suitable for MS Excel, which works out of
the box or you can try native experimental MS Excel exporter. For
enabling this you need to set $cfg['TempDir'] to place where web
server user can write (for example './tmp') and install PEAR module
Spreadsheet_Excel_Writer into php include path. The installation can
be done by following command:
pear -d preferred_state=beta install -a Spreadsheet_Excel_Writer
First part of switches set we want to install beta version of that
module (no stable version available yet) and then we tell pear we want
to satisfy dependencies.
If you are running in PHP safe mode, you will have to set in php.ini
the safe_mode_include_dir to the directory where your PEAR modules are
located, for example:
safe_mode_include_dir = /usr/local/lib/php
To create the temporary directory on a UNIX-based system, you can do:
cd phpMyAdmin
mkdir tmp
chmod o+rwx tmp
[7. phpMyAdmin project]
[7.1] I have found a bug. How do I inform developers?
Our Bug Tracker is located at
http://sourceforge.net/projects/phpmyadmin/ under the Bugs section.
But please first discuss your bug with other users:
http://sourceforge.net/projects/phpmyadmin/ (and choose Forums)
[7.2] I want to translate the messages to a new language or upgrade an
existing language, where do I start?
Always use the current CVS version of your language file. For a new
language, start from english-iso-8859-1.inc.php. If you don't know how
to get the CVS version, please ask one of the developers.
Please note that we try not to use HTML entities like é in the
translations, since we define the right character set in the file.
With HTML entities, the text on JavaScript messages would not display
correctly. However there are some entities that need to be there, for
quotes ,non-breakable spaces, ampersands, less than, greater than.
You can then put your translations, as a zip file to avoid losing
special characters, on the sourceforge.net translation tracker.
It would be a good idea to subscribe to the phpmyadmin-translators
mailing list, because this is where we ask for translations of new
messages.
[7.3] I would like to help out with the development of phpMyAdmin. How
should I proceed?
The following method is preferred for new developers:
1. fetch the current CVS tree over anonymous CVS:
cvs
-d:pserver:anonymous@cvs.phpmyadmin.sourceforge.net:/cvsroot/phpmy
admin login
[Password: simply press the Enter key]
cvs -z3
-d:pserver:anonymous@cvs.phpmyadmin.sourceforge.net:/cvsroot/phpmy
admin checkout phpMyAdmin
[This will create a new sub-directory named phpMyAdmin]
2. add your stuff
3. put the modified files (tar'ed and gzip'ed) inside the patch
tracker of the phpMyAdmin SourceForge account.
Write access to the CVS tree is granted only to experienced developers
who have already contributed something useful to phpMyAdmin.
Also, have a look at the Developers section.
[8. Security ]
[8.1] Security alert, dated 2003-06-18.
Last update of this FAQ: 2003-07-22.
The phpMyAdmin development team received notice of this security
alert: http://www.securityfocus.com/archive/1/325641.
The team regrets that the author did not communicate with us before
sending this alert. However, here is our current reply to the points
mentionned:
* "Directory transversal attack"
This problem had been fixed in version 2.5.0, even if the author
reports the 2.5.2 development version as vulnerable, which we
could not reproduce.
* "Remote local file retrieving"
This is a misleading title, as the author tells in his text: "Note
that you can't request files ( only dirs )".
* "Remote internal directory listing"
It was possible to retrieve the list of phpMyAdmin's directory
(which we doubt can cause any damage), but we fixed this in the
2.5.2 version.
* "XSS and Path disclosures"
Most of the XSS problems have been fixed in version 2.5.0. The
rest have been fixed in the 2.5.2 version.
We believe that the Path disclosures problems have also been fixed
in version 2.5.2.
* "Information encoding weakness"
We believe that an exploit for this weakness would be difficult to
achieve. However version 2.5.2 now encrypts the password with the
well-known blowfish algorithm.
[8.2] Security alert, dated 2004-06-29.
Last update of this FAQ: 2004-06-30.
The phpMyAdmin development team received notice of this security
alert:
http://securityfocus.com/archive/1/367486/2004-06-26/2004-07-02/0
We would like to put emphasis on the disappointment we feel when a
bugreporter does not contact the authors of a software first, before
posting any exploits. The common way to report this, is to give the
developers a reasonable amount of time to respond to an exploit before
it is made public.
We acknowledge that phpMyAdmin versions 2.5.1 to 2.5.7 are vulnerable
to this problem, if each of the following conditions are met:
* The Web server hosting phpMyAdmin is not running in safe mode.
* In config.inc.php, $cfg['LeftFrameLight'] is set to FALSE (the
default value of this parameter is TRUE).
* There is no firewall blocking requests from the Web server to the
attacking host.
Version 2.5.7-pl1 was released with a fix for this vulnerability.
Developers Information
phpMyAdmin is Open Source, so you're invited to contribute to it. Many
great features have been written by other people and you too can help
to make phpMyAdmin a useful tool.
If you're planning to contribute source, please read the following
information:
* All files include header.inc.php (layout),
libraries/common.lib.php (common functions) and config.inc.php.
Only configuration data should go in config.inc.php. Please keep
it free from other code.
Commonly used functions should be added to
libraries/common.lib.php and more specific ones may be added
within a library stored into the libraries sub-directory.
* Obviously, you're free to use whatever coding style you want. But
please try to keep your code as simple as possible: beginners are
using phpMyAdmin as an example application.
As far as possible, we want the scripts to be XHTML1.0 and CSS2
compliant on one hand, they fit the PEAR coding standards on the
other hand. Please pay attention to this.
* Please try to keep up the file-naming conventions. Table-related
stuff goes to tbl_*.php, db-related code to db_*.php,
server-related tools to server_*.php and so on.
* Please don't use verbose strings in your code, instead add the
string (at least) to english-iso-8859-1.inc.php and print() it
out.
* If you want to be really helpful, write an entry for the
ChangeLog.
* The DBG extension (PHP Debugger DBG) is now supported by
phpMyAdmin for developers to better debug and profile their code.
Please see the $cfg['DBG']* configuration options for more
information.
This is in memoriam of the Space Shuttle Columbia (STS-107) which
was lost during its re-entry into Earth's atmosphere and in memory
of the brave men and women who gave their lives for the people of
Earth.

Original Credits of Version 2.1.0
---------------------------------
This work is based on Peter Kuppelwieser's MySQL-Webadmin. It was his idea
to create a web-based interface to MySQL using PHP3. Although I have not
used any of his source-code, there are some concepts I've borrowed from
him. phpMyAdmin was created because Peter told me he wasn't going to
further develop his (great) tool.
Thanks go to
- Amalesh Kempf <ak-lsml_at_living-source.com> who contributed the
code for the check when dropping a table or database. He also suggested
that you should be able to specify the primary key on tbl_create.php3. To
version 1.1.1 he contributed the ldi_*.php3-set (Import text-files) as
well as a bug-report. Plus many smaller improvements.
- Jan Legenhausen <jan_at_nrw.net>: He made many of the changes that
were introduced in 1.3.0 (including quite significant ones like the
authentication). For 1.4.1 he enhanced the table-dump feature. Plus
bug-fixes and help.
- Marc Delisle <DelislMa_at_CollegeSherbrooke.qc.ca> made phpMyAdmin
language-independent by outsourcing the strings to a separate file. He
also contributed the French translation.
- Alexandr Bravo <abravo_at_hq.admiral.ru> who contributed
tbl_select.php3, a feature to display only some fields from a table.
- Chris Jackson <chrisj_at_ctel.net> added support for MySQL
functions in tbl_change.php3. He also added the
"Query by Example" feature in 2.0.
- Dave Walton <walton_at_nordicdms.com> added support for multiple
servers and is a regular contributor for bug-fixes.
- Gabriel Ash <ga244_at_is8.nyu.edu> contributed the random access
features for 2.0.6.
