Memcached::__construct — Create a Memcached instance
Creates a Memcached instance representing the connection to the memcache servers.
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.
A Memcached object.
