   * This is only an example. 	*/

 /**
  * The following will initialize a Memcached client to utilize the Auto Discovery feature.
  * 
  * By configuring the client with the Dynamic client mode with single endpoint, the
  * client will periodically use the configuration endpoint to retrieve the current cache
  * cluster configuration. This allows scaling the cache cluster up or down in number of nodes
  * without requiring any changes to the PHP application. 
  *
  * 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. 
  * See http://php.net/manual/en/memcached.construct.php for more information.
  */
  $dynamic_client = new Memcached('persistent-id');
  $dynamic_client->setOption(Memcached::OPT_CLIENT_MODE, Memcached::DYNAMIC_CLIENT_MODE);
  $dynamic_client->addServer($server_endpoint, $server_port);
  
  /**
  * Store the data for 60 seconds in the cluster. 
  * The client will decide which cache host will store this item.
  */  
  $dynamic_client->set('key', 'value', 60);  


 /**
  * Configuring the client with Static client mode disables the usage of Auto Discovery
  * and the client operates as it did before the introduction of Auto Discovery. 
  * The user can then add a list of server endpoints.
  */
  $static_client = new Memcached('persistent-id');
  $static_client->setOption(Memcached::OPT_CLIENT_MODE, Memcached::STATIC_CLIENT_MODE);
  $static_client->addServer($server_endpoint, $server_port);

 /**
  * Store the data without expiration.
