MySQL is no longer enabled by default, so the
php_mysql.dll
DLL must be enabled
inside of php.ini
. Also, PHP needs
access to the MySQL client library. A file named
libmysql.dll
is included in the Windows
PHP distribution and in order for PHP to talk to MySQL this
file needs to be available to the Windows systems
PATH
. See the FAQ titled
"How
do I add my PHP directory to the PATH
on
Windows" for information on how to do this.
Although copying libmysql.dll
to the
Windows system directory also works (because the system
directory is by default in the system's
PATH
), it's not recommended.
As with enabling any PHP extension (such as
php_mysql.dll
), the PHP directive
extension_dir
should be set to the directory where the PHP extensions are
located. See also the
Manual
Windows Installation Instructions. An example
extension_dir value for PHP 5 is
c:\php\ext
If when starting the web server an error similar to the
following occurs: "Unable to load dynamic
library './php_mysql.dll'"
, this
is because php_mysql.dll
and/or
libmysql.dll
cannot be found by the
system.

The MySQL Native
Driver is enabled by default. Include
php_mysql.dll
, but
libmysql.dll
is no longer required or
used.
