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 .
This module uses functions of
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.

In order to use these functions you must compile PHP with MemCache support
by using the --with-memcache[=DIR] option.
Windows users will enable php_memcache.dll inside
of php.ini in order to use these functions.

There is only one resource type used in memcache module - it's
the link identifier for a cache server connection.
例 1. memcache extension overview example |
<?php
$memcache = new Memcache;
$memcache->connect('localhost', 11211) or die ("Could not connect");
$version = $memcache->getVersion();
echo "Server's version: ".$version."<br/>\n";
$tmp_object = new stdClass;
$tmp_object->str_attr = 'test';
$tmp_object->int_attr = 123;
$memcache->set('key', $tmp_object, false, 10) or die ("Failed to save data at the server");
echo "Store data in the cache (data will expire in 10 seconds)<br/>\n";
$get_result = $memcache->get('key');
echo "Data from the cache:<br/>\n";
var_dump($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.
