Database Reference
In-Depth Information
This script displays information about the PHP component, including the
available extensions. We should at least see a section about MySQL (proving that
the
mysql
extension is available), which gives information about the MySQL
Client
API version
.
We can also try other PHP scripts that make a connection to MySQL, to see if the
problem is more general than just phpMyAdmin not working. As a general rule,
we should be running the latest stable versions of every component.
Base configuration
We should always double-check the way we made the installation, including proper
permissions and ownerships. Typos may occur while modifying
config.inc.php
.
Solving common errors
To help solve a problem, we should first pinpoint the origin of the error message.
Here are the various components that can generate an error message:
•
MySQL server: These messages are relayed by phpMyAdmin, which displays
MySQL said
followed by the message
PHP component of the web server: For example,
•
Parser error
Web server: The error can be seen from the browser, or in the web server's
•
log files.
Web browser: For example, JavaScript errors
•
The
Error Messages
and
Other Problems
sections are mostly based on various
messages found on phpMyAdmin's help forum and in the FAQ section of
Documentation.html
.
Error messages
This section refers to explicit error messages, as displayed by phpMyAdmin.
Cannot load MySQL extension
To connect to a MySQL server, PHP needs the
mysql
extension
(
mysqli
extension
is recommended for MySQL 4.1+
)
, which is a set of MySQL functions. This
extension may be compiled as a part of the PHP server. Or it may need to be loaded
dynamically, in which case, phpMyAdmin may have tried to load it and failed. This
error implies that no other PHP script can make connections to a MySQL server.
