PHP 5.3.6 or newer. Some advanced functionality requires PHP 5.4.0 or newer.
The mysqlnd_ms replication and load balancing plugin supports all PHP applications and all available PHP MySQL extensions (mysqli, mysql, PDO_MYSQL). The PHP MySQL extension must be configured to use mysqlnd in order to be able to use the mysqlnd_ms plugin for mysqlnd.
