&Changelog; &Version; &Description; 5.3.0 The MySQL Native Driver was added, with support for all MySQL extensions (i.e., mysql, mysqli and PDO_MYSQL). Passing in mysqlnd to the appropriate configure switch enables this support. 5.4.0 The MySQL Native Driver is now the default for all MySQL extensions (i.e., mysql, mysqli and PDO_MYSQL). Passing in mysqlnd to configure is now optional. Installation on Unix The MySQL database extensions must be configured to use the MySQL Client Library. In order to use the MySQL Native Driver, PHP needs to be built specifying that the MySQL database extensions are compiled with MySQL Native Driver support. This is done through configuration options prior to building the PHP source code. For example, to build the MySQL extension, mysqli and PDO MYSQL using the MySQL Native Driver, the following command would be given: ./configure --with-mysql=mysqlnd \ --with-mysqli=mysqlnd \ --with-pdo-mysql=mysqlnd \ [other options] Installation on Windows In the official PHP Windows distributions from 5.3 onwards, MySQL Native Driver is enabled by default, so no additional configuration is required to use it. All MySQL database extensions will use MySQL Native Driver in this case.
