Memcached::getServerByKey — Map a key to a server

Açıklama

public array Memcached::getServerByKey ( string $server_key )

Memcached::getServerByKey() returns the server that would be selected by a particular server_key in all the Memcached::*ByKey() operations.

Değiştirgeler

server_key: The key identifying the server to store the value on or retrieve it from. Instead of hashing on the actual key for the item, we hash on the server key when deciding which memcached server to talk to. This allows related items to be grouped together on a single server for efficiency with multi operations.

Dönen Değerler

Returns an array containing three keys of host, port, and weight on success or FALSE on failure. Gerekirse Memcached::getResultCode() kullanın.
