Creates a Memcached instance representing the connection to the memcache
servers.
Parameters
persistent_id
By default the Memcached instances are destroyed at the end of the
request. To create an instance that persists between requests, use
persistent_id to specify a unique ID for the
instance. All instances created with the same
persistent_id will share the same connection.
Return Values
A Memcached object.
Examples
Example #1 Creating a Memcached object
<?php /* Create a regular instance */ $m = new Memcached(); echo get_class($m);
/* Create a persistent instance */ $m2 = new Memcached('story_pool'); $m3 = new Memcached('story_pool');
/* now $m2 and $m3 share the same connection */ ?>
