Chapter 23
Caching
Introduction
Doctrine_Cache offers an intuitive and easy-to-use query caching solution. It provides the
following things:
• Multiple cache backends to choose from (including Memcached, APC and Sqlite)
• Advanced options for fine-tuning. Doctrine_Cache has many options for finetuning
performance.
All the cache drivers are instantiated like the following:
Listing
23-1
// bootstrap.php
// ...
$options = array();
$cacheDriver = new Doctrine_Cache_Memcache($options);
Each driver has its own possible values for the $options array.
Drivers
Memcache
Memcache driver stores cache records into a memcached server. Memcached is a highperformance,
distributed memory object caching system. In order to use this backend, you
need a memcached daemon and the memcache PECL extension.
You can instantiate the Memcache cache driver with the following code:
Listing
23-2
// bootstrap.php
// ...
$servers = array(
'host' => 'localhost',
'port' => 11211,
'persistent' => true
);
