Memcached::addServers — Add multiple servers to the server pool
Memcached::addServers() adds servers to the server pool. Each entry in servers is supposed to an array containing hostname, port, and, optionally, weight of the server. No connection is established to the servers at this time.
The same server may appear multiple times in the server pool, because no duplication checks are made. This is not advisable; instead, use the weight option to increase the selection weighting of this server.
Array of the servers to add to the pool.
如果成功则返回 TRUE，失败则返回 FALSE。
