phpMyAdmin 2.4.1-dev Documentation
Requirements
- PHP3 or PHP4: phpMyAdmin widely uses the 'str_replace()' php function that
was added in PHP 3.0.6, but was buggy up until PHP 3.0.8. Then you should not run this script with
PHP3 < 3.0.8.
PHP also needs to be compiled with MySQL support;
- MySQL (tested with 3.21.x, 3.22.x, 3.23.x and 4.0.x);
Note: Because of a major change in the definition syntax of
string field types, this version of phpMyAdmin probably won't work correctly
with MySQL >= 4.1.0!
- 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
- 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
- communicate in 42 different
languages
Installation
NOTE: phpMyAdmin does not apply any special security
methods to the MySQL database server. It is still the sysadmin'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").
Documentation warning: when you see in this
document a .php3 file extension, please transpose to .php if you
are using a kit with files having this extension.
Quick Install:
- Choose and download a distribution kit with the files having the extension
(.php3 or .php) depending on the way your web/PHP server
interprets those extensions.
- 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.
- Open the file config.inc.php3 in your favourite 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.
- 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 FAQ
section for additional information.
- Open the file
<www.your-host.com>/<your-install-dir>/index.php3 in your
browser. phpMyAdmin should now display a welcome screen and your databases, or
a login dialog if using http or cookie authentication mode.
Upgrading from an older version:
- Please do not copy your older config.inc.php3 over the new one: it may
offer new configuration variables, and the new version may depend on these for
normal behavior. It is suggested instead to insert your site values in the new
one.
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, we send the
password in a temporary cookie, so most browsers should not store the password
in their cookie file.
- 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.tables_priv (all columns except "Grantor" & "Timestamp")
tables.
You must specify the details for the controluser in the
config.inc.php3 file under the
$cfg['Servers'][$i]['controluser']&
$cfg['Servers'][$i]['controlpass'] settings.
This 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:
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)
ON mysql.user TO 'pma'@'localhost';
GRANT SELECT ON mysql.db TO 'pma'@'localhost';
GRANT SELECT (Host, Db, User, Table_name, Table_priv, Column_priv)
ON mysql.tables_priv 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)
- 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 auth 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.
'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 use can truly logout of phpMyAdmin and login back with
the same username.
'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.
All configurable data is placed in config.inc.php3.
- $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.
Alternatively, this setting can be dynamically
completed. For example, you can try to use such a kind of code: $cfg['PmaAbsoluteUri'] = (!empty($_SERVER['HTTPS']) ? 'https' : 'http') . '://'
. $_SERVER['HTTP_HOST']
. (!empty($_SERVER['SERVER_PORT']) ? ':' . $_SERVER['SERVER_PORT'] : '')
. substr($_SERVER['PHP_SELF'], 0, strrpos($_SERVER['PHP_SELF'], '/')+1);
or
$cfg['PmaAbsoluteUri'] = (!empty($_SERVER['HTTPS']) ? 'https' : 'http') . '://'
. $_SERVER['SERVER_NAME']
. (!empty($_SERVER['SERVER_PORT']) ? ':' . $_SERVER['SERVER_PORT'] : '')
. substr($_SERVER['SCRIPT_NAME'], 0, strrpos($_SERVER['SCRIPT_NAME'], '/')+1);
Please note that the $_SERVER array doesn't exist in
PHP < 4.1.0. Try to replace $_SERVER by
$HTTP_SERVER_VARS or $GLOBALS in this case.
- $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['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 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).
- $cfg['Servers'][$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
guarenteed 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]['compress'] boolean
- Wheather 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
- 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 http authentication" 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 ($auth_type = 'config') is
the plain old way: username and password are stored in
config.inc.php3.
- 'cookie' authentication mode ($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.
- '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 wilcards characters ("_" and "%"): if you want to
use literal instances of these characters, escape them (ie use
'my\_db' and not 'my_db').
This setting is an efficient
way to lower the server charge 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 at all other databases can't be used.
- $cfg['Servers'][$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 pulldown 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
- Starting with version 2.3.0 phpMyAdmin offers a lot of features to work
with master / foreign - tables. To use those as well as the bookmark feature
you need special tables with a predefined structure, which we explain
below.
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'].
If you are setting up a multi-user phpMyAdmin installation, you will
need to create a new db and setup special privileges, so, as superuser:
- create a new database for phpmyadmin:
CREATE DATABASE
phpmyadmin;
Note that "controluser" must have SELECT, INSERT,
UPDATE and DELETE privileges on this database. Here is a query
to set up those privileges (using "phpmyadmin" as the database name, and
"pma" as the controluser):
GRANT
SELECT,INSERT,UPDATE,DELETE ON phpmyadmin.* to 'pma'@'localhost';
do not give any other user rights on this database.
- enter the databasename in $cfg['Servers'][$i]['pmadb']
$cfg['Servers'][$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 you have to:
- set up "pmadb" as described above
- within this database create a table following this scheme:
CREATE TABLE `PMA_bookmark`
(
id int(11) DEFAULT '0' NOT
NULL auto_increment,
dbase
varchar(255) NOT NULL,
user
varchar(255) NOT NULL,
label
varchar(255) NOT NULL,
query
text NOT NULL,
PRIMARY KEY
(id)
) TYPE=MyISAM
COMMENT='Bookmarks';
- enter the tablename 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 tooltip 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);
- 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 an example in the FAQ,
section "Using phpMyAdmin");
- 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 the superuser has to:
- set up "pmadb" as described above
- within this database create a table following this scheme:
CREATE TABLE `PMA_relation`
(
`master_db` varchar(64) NOT
NULL default '',
`master_table`
varchar(64) NOT NULL default
'',
`master_field` varchar(64)
NOT NULL default
'',
`foreign_db` varchar(64)
NOT NULL default
'',
`foreign_table` varchar(64)
NOT NULL default
'',
`foreign_field` varchar(64)
NOT NULL default '',
PRIMARY
KEY (`master_db`, `master_table`,
`master_field`),
KEY
foreign_field (foreign_db, foreign_table)
)
TYPE=MyISAM COMMENT='Relation table';
- 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 (2.3.0) 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 tooltip 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 the superuser has to:
- set up "pmadb" as described above
- within this database create a table following this scheme:
CREATE TABLE `PMA_table_info`
(
`db_name` varchar(64) NOT
NULL default '',
`table_name`
varchar(64) NOT NULL default
'',
`display_field` varchar(64)
NOT NULL default '',
PRIMARY
KEY (`db_name`, `table_name`)
) TYPE=MyISAM
COMMENT='Table information for phpMyAdmin';
- 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 and have a table of PDF pages
(see $cfg['Servers'][$i]['pdf_pages']) to create PDF output.
To allow the usage of this functionality the superuser has to:
- set up "pmadb" as described above
- within this database create a table following this scheme:
CREATE TABLE `PMA_table_coords`
(
`db_name` varchar(64) NOT
NULL default '',
`table_name`
varchar(64) NOT NULL default
'',
`pdf_page_number` int NOT
NULL default '0',
`x` float
unsigned NOT NULL default
'0',
`y` float unsigned NOT
NULL default '0',
PRIMARY KEY
(`db_name`, `table_name`,
`pdf_page_number`)
) TYPE=MyISAM
COMMENT='Table coordinates for phpMyAdmin PDF output';
- also within this database
create:
CREATE TABLE `PMA_pdf_pages`
(
`db_name` varchar(64) NOT
NULL default '',
`page_nr`
int(10) unsigned NOT NULL
auto_increment,
`page_descr`
varchar(50) NOT NULL default
'',
PRIMARY KEY
(page_nr),
KEY
(db_name)
) TYPE=MyISAM COMMENT='PDF
Relationpages for PMA';
- put the first table name in $cfg['Servers'][$i]['table_coords']
and the second table name in $cfg['Servers'][$i]['pdf_pages']
Usage tips: PDF output.
$cfg['Servers'][$i]['column_comments']
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".
To allow the
usage of this functionality the superuser has to:
- set up "pmadb" as described above
- within this database create a table following this scheme:
CREATE TABLE `PMA_column_comments`
(
id int(5) unsigned NOT NULL
auto_increment,
db_name
varchar(64) NOT NULL default
'',
table_name varchar(64) NOT
NULL default '',
column_name
varchar(64) NOT NULL default
'',
`comment` varchar(255) NOT
NULL default '',
PRIMARY KEY
(id),
UNIQUE KEY db_name
(db_name, table_name, column_name)
)
TYPE=MyISAM COMMENT='Comments for Columns';
- put the table name in $cfg['Servers'][$i]['column_comments']
- $cfg['Servers'][$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'] boolean
- Defines whether to use gzip output buffering for increased speed in HTTP
transfers.
- $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 loose 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['LeftFrameLight'] boolean
- Defines whether to use select-based menu and display only the current
tables in the left frame (smaller page).
- $cfg['ShowTooltip'] boolean
- Defines whether to display table comment as tooltip in left frame or not.
- $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 resultset. If the resultset
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 -ie
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/bzip compression when
creating a dump file or not.
- $cfg['DefaultTabDatabase'] string
- Defines the tab displayed by default on database view. Possible values:

$cfg['MySQLManualType']), appropriate help links are generated.
See MySQL
Documentation page for more information about MySQL manuals and their
types.
- $cfg['MySQLManualType'] string
- Type of MySQL documentation:
- old - old style used in phpMyAdmin 2.3.0 and sooner
- searchable - "Searchable, with user comments"
- chapters - "HTML, one page per chapter"
- big - "HTML, all on one page"
- none - do not show documentation links

- Defines the default language to use, if not browser-defined or
user-defined.
See the select_lang.inc.php3 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.php3 script).
- $cfg['DefaultCharset'] string
- Default charset to use for recoding of MySQL queries. This must be enabled
and it's described by $cfg['AllowAnywhereRecoding'] option.
You
can give here any charset which is in $cfg['AvailableCharsets'] array
and this is just default choice, user can select any of them.
- $cfg['AllowAnywhereRecoding'] boolean
- Allow charset 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 charset 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['AvailableCharsets'] array
- Available charsets for MySQL conversion. You can add your own (any of
supported by recode/iconv) or remove these which you don't use. Charsets will
be shown in same order as here listed, so if you frequently use some of these
move them to the top.
- $cfg['LeftWidth'] integer
- Left frame width in pixel.
- $cfg['LeftBgColor'] string [HTML color]
$cfg['RightBgColor']
string [HTML color]

- $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 NS4).
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.
You can disable both of these features by emptying the respective
directive.
- $cfg['TextareaCols'] integer
$cfg['TextareaRows']
integer
$cfg['CharTextareaCols']
integer
$cfg['CharTextareaRows'] integer
- Number of columns and rows for the textareas.

and VARCHAR editing (if configured via $cfg['CharEditing']).
- $cfg['TextareaAutoSelect'] boolean
- Defines if the whole textarea of the query box will be selected on click.
- $cfg['LimitChars'] integer
- Maximal number of Chars showed in a TEXT OR a BLOB field

display mode.
- $cfg['DefaultDisplay'] string
- There are 2 display modes: horizontal and vertical. Define which one is
displayed by default.
- $cfg['UploadDir'] string
- The name of the directory, ending with a slash, 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".
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['RepeatCells'] integer
- Repeat the headers every X cells, or 0 to deactivate.
- $cfg['SQP']['enable'] boolean
- As of phpMyAdmin 2.3.0, we now have a fully functional SQL Parser system.
It is enabled by default, as it is used to format the SQL queries.
As of
2.3.1, it will become an integral part of phpMyAdmin, as it will analyze
certain queries to improve the behavior of phpMyAdmin. But as it is very new,
and not yet heavily used, we offer you an option to turn it off.
- $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 varible 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 "/*...*/"

- $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 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.

[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 or .php3 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 workaroud (at this time
there is no better fix): remove or comment the DOCTYPE declarations (2
lines) from the scripts header.inc.php3,
header_printview.inc.php3, index.php3, left.php3 and
libraries/common.lib.php3.
[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 IE 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.
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.
[1.17] Does phpMyAdmin support MySQL 4.1?
Because of a major change in the definition syntax of string field types,
this version of phpMyAdmin probably won't work correctly with
MySQL >= 4.1.0! We will work on the support as soon as
MySQL 4.1.0 is released.
[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 server (compiled-in),
otherwise it needs to be loaded dynamically. Its name is probably
mysql.so or 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 you
my.ini file that should be located in your Windows directory and add
the following line:
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
"IUSER_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.php3 with plenty of dabases).
This is a PHP bug that occur when
GZIP output buffering enabled. If you turn off it (by $cfg['OBGzip'] =
FALSE in config.inc.php3), 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 bugfix available starting
with MySQL 3.23.56 / 4.0.11-gamma.
[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 .php3 file and ensure there is nothing (ie
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.php3.
For example:
$cfg['Servers'][$i]['socket'] = '/tmp/mysql.sock';
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.
[3. Known limitations]
[3.1] When using http authentication, an user who logged out can not relog
in with the same nick.
This is related to the authentication mechanism (protocol) used by
phpMyAdmin. We plan to change it as soon as we may find enough free time to do
it, but you can bypass this problem: just close all the opened browser windows
and then go back to phpMyAdmin. You should be able to logs in again.
[3.2] When dumping a large table in compressed mode, I get a memory limit
error or a time limit error.
As of version 2.2.4, we build the compressed dump in memory, so large tables
dumps may hang. The only alternative we can think about (using system calls to
mysqldump then gzip or bzip2) would not be applicable in environments where PHP
is in safe mode: access to system programs is is limited by the system
administrator, and time limit is enforced.
[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?). However, keep in
mind that phpMyAdmin as of version 2.3.0 does not support InnoDB.
[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 to dashes of the line or add a # before it:
--
-------------------------------------------------------
or
#---------------------------------------------------------
[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.php3 file should be chmod 660.
- All your phpMyAdmin files should be chown 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.php3 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, 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',
);
[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 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 lenght 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 charset 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.
[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.
[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.
[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
- Choose this page to edit
- Now add a table you want to show on this page and it's coordinates and
submit
First you will have to guess this 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 than it will
automatically be scaled but 300*100 is a good start to have an idea of what
coordinates to use.
- 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] My database has an underscore in it's name, and when I grant
privileges to a user for this database, a backslash is added before the
underscore.
This is normal and means that the grant is done only for this database. If
there was no backslash, this would be a wildcard grant, and the underscore would
mean "any character". So, if the database name is "john_db", the user would get
rights to john1db, john2db... instead of just john_db.
If you really want
to grant using a wildcard, there is a dialog box " Database (wildcards allowed)"
for this.
[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.
[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
nessecary PEAR modules for usage.
If you use it, 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.).
[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.php3. 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:
- fetch the current CVS tree over anonymous CVS:
cvs
-d:pserver:anonymous@cvs.phpmyadmin.sourceforge.net:/cvsroot/phpmyadmin
login
[Password: simply press the Enter key]
cvs -z3
-d:pserver:anonymous@cvs.phpmyadmin.sourceforge.net:/cvsroot/phpmyadmin
checkout phpMyAdmin
[This will create a new sub-directory named
phpMyAdmin]
- add your stuff
- 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.
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.php3 (layout),
libraries/common.lib.php3 (common functions) and
config.inc.php3.
All configuration data belongs in
config.inc.php3. Please keep it free from other code.
Commonly used
functions should be added to libraries/common.lib.php3 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_*.php3, db-related code to db_*.php3, server-related
tools to server_*.php3 and so on.
- Please don't use verbose strings in your code, instead add the string (at
least) to english-iso-8859-1.inc.php3 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 memorium 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.
The following people have contributed minor changes, enhancements, bugfixes
or support for a new language:
Jim Kraai, Jordi Bruguera, Miquel Obrador, Geert Lund, Thomas Kleemann,
Alexander Leidinger, Kiko Albiol, Daniel C. Chao, Pavel Piankov,
Sascha Kettler, Joe Pruett, Renato Lins, Mark Kronsbein, Jannis Hermanns,
G. Wieggers.
And thanks to everyone else who sent me email with suggestions, bug-reports
and or just some feedback.
