Try it out at the demo page.

and one or more of the supported caches

  • PHP OpCache (opcache extension for php5, included by default in php5.5+)
  • APC or APCu extension
  • Realpath cache ( available since PHP 5.3.2+ )
  • Memcache (partially) and Memcached extension
  • Redis

Supported operations

  • View memory statistics
  • View hit rate
  • Select keys based on regular expression
  • Delete keys based on regular expression
  • Selecting all keys
  • Deleting keys without regular expressions
  • Sort on any data column

Configuring caches

Information about specific caches can be disabled by setting the ENABLE_<cache> key to false. The default code tests whether the specific cache is available and supported before enabling it.

APC / APCu

<?php
// Enable APC
define('ENABLE_APC', true);

// Disable APC
define('ENABLE_APC', false);

OPcache

<?php
// Enable OPcache
define('ENABLE_OPCACHE', true);

// Disable OPcache
define('ENABLE_OPCACHE', false);

Realpath

<?php
// Enable Realpath
define('ENABLE_REALPATH', true);

// Disable Realpath
define('ENABLE_REALPATH', false);

Redis

<?php
// Enable Redis
define('ENABLE_REDIS', true);

// Disable Redis
define('ENABLE_REDIS', false);

Redis configuration can be done by either changing the REDIS_ constants or by setting the environment variables with the same name.

Environment Variable Default Description
REDIS_HOST 127.0.0.1 The hostname of the redis instance to connect to
REDIS_PORT 6379 The TCP port number on which Redis is listening for connections
REDIS_PASSWORD null The password used to connect
REDIS_DATABASE null Set this to the database number if you want to lock the database number
REDIS_SIZE null The size of your Redis database in bytes if total size is detected incorrectly
