Memcached::getByKey — Retrieve an item from a specific server

Beschreibung

public mixed Memcached::getByKey ( string $server_key , string $key [, callback $cache_cb [, double &$cas_token ]] )

Memcached::getByKey() is functionally equivalent to Memcached::get, except that the free-form server_key can be used to map the key to a specific server.

Parameter-Liste

server_key: The key identifying the server to fetch the item from.
key: The key of the item to fetch.
cache_cb: Read-through caching callback or NULL
cas_token: The variable to store the CAS token in.

Rückgabewerte

Returns the value stored in the cache or FALSE otherwise. The Memcached::getResultCode will return Memcached::RES_NOTFOUND if the key does not exist.
