Warning
This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide. Alternatives to this function include:
For compiling, simply use the
--with-mysql[=DIR] configuration option where
the optional [DIR] points to the MySQL
installation directory.
Although this MySQL extension is compatible with MySQL 4.1.0 and greater, it doesn't support the extra functionality that these versions provide. For that, use the MySQLi extension.
If you would like to install the mysql extension along with the mysqli extension you have to use the same client library to avoid any conflicts.
Copyright 1997-2021 the PHP Documentation Group.
Note: [DIR] is the path to the MySQL client
library files (headers and libraries),
which can be downloaded from
MySQL.

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
Note
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.

Warning
Crashes and startup problems of PHP may be encountered when loading this extension in conjunction with the recode extension. See the recode extension for more information.
Note
If you need charsets other than latin (default), you have to install external (not bundled) libmysqlclient with compiled charset support.
