Memcached::casByKeyCompare and swap an item on a specific server

Descrierea

public bool Memcached::casByKey ( double $cas_token , string $server_key , string $key , mixed $value [, int $expiration ] )

Memcached::casByKey() is functionally equivalent to Memcached::cas, except that the free-form server_key can be used to map the key to a specific server. This is useful if you need to keep a bunch of related keys on a certain server.

Întoarce valoarea TRUE în cazul succesului sau FALSE în cazul eşecului. The Memcached::getResultCode will return Memcached::RES_DATA_EXISTS if the item you are trying to store has been modified since you last fetched it.
