Memcached::replaceByKey — Replace the item under an existing key on a specific server

Описание

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

Memcached::replaceByKey() is functionally equivalent to Memcached::replace, 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.

Список параметров

server_key: The key identifying the server to store the value on.
key: The key under which to store the value.
value: The value to store.
expiration: The expiration time, defaults to 0. See Expiration Times for more info.

Возвращаемые значения

Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки. The Memcached::getResultCode will return Memcached::RES_NOTSTORED if the key does not exist.
