PHP 5.3.3
or a newer version of
PHP
.
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.
For using
MEMCACHE
storage handler: Use
libmemcache 0.38
or newer. PECL/mysqlnd_qc 1.2 has
been tested with
libmemcache 1.4.0
.
For using
sqlite
storage handler: Use the sqlite3 extension that bundled with PHP.
