PECL/mysqlnd_qc is a mysqlnd plugin. It plugs into the mysqlnd library. To use you this plugin with a PHP MySQL extension, the extension (mysqli, mysql, or PDO_MYSQL) must enable the mysqlnd library.

For using the APC storage handler with PECL/mysqlnd_qc 1.0 `APC 3.1.3p1-beta` or newer. PECL/mysqlnd_qc 1.2 has been tested with `APC 3.1.13-beta`. The APC storage handler cannot be used with a shared build. You cannot use the PHP configuration directive `extension` to load the APC and PECL/mysqlnd_qc extensions if PECL/mysqlnd_qc will use APC as a storage handler. For using the APC storage handler, you have to statically compile PHP with APC and PECL/mysqlnd_qc support into PHP.
