Memcache

&reftitle.intro; Memcache module provides handy procedural and object oriented interface to memcached, highly effective caching daemon, which was especially designed to decrease database load in dynamic web applications. More information about memcached can be found at &url.memcache;.

&reftitle.required; This module uses functions of zlib to support on-the-fly data compression. Zlib is required to install this module. PHP 4.3.3 or newer is required to use the memcache extension.

&reftitle.runtime; &no.config;

&reftitle.resources; There is only one resource type used in memcache module - it's the link identifier for a cache server connection.

&reftitle.examples; connect('localhost', 11211) or die ("Could not connect"); $version = $memcache->getVersion(); echo "Server's version: ".$version."
\n"; $tmp_object = new stdClass; $tmp_object->str_attr = 'test'; $tmp_object->int_attr = 123; $memcache->set('key', $tmp_object, 10) or die ("Failed to save data at the server"); echo "Store data in the cache (data will expire in 10 seconds)
\n"; $get_result = $memcache->get('key'); echo "Data from the cache:
\n"; var_dump($get_result); ?> ]]> In the above example, an object is being saved in the cache and then retrieved back. Object and other non-scalar types are serialized before saving, so it's impossible to store resources (i.e. connection identifiers and others) in the cache.
