Memcached::deleteMultiByKey

(PECL memcached >= 2.0.0)

Memcached::deleteMultiByKeyDelete multiple items from a specific server

Descrizione

public Memcached::deleteMultiByKey(string $server_key, array $keys, int $time = 0): bool

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

Elenco dei parametri

server_key

La chiave che identifica il server su cui salvare il valore. Invece di effettuare li'hashing sulla chiave dell'elemento, si effettua l'hashing della chiave del server al momento di decidere con quale server memcached comunicare. Questo permette di raggruppare gli elementi correlati ad un singolo server ottenendo maggiore efficienza nelle operazioni multiple.

keys

The keys to be deleted.

time

The amount of time the server will wait to delete the items.

Nota: As of memcached 1.3.0 (released 2009) this feature is no longer supported. Passing a non-zero time will cause the deletion to fail. Memcached::getResultCode() will return MEMCACHED_INVALID_ARGUMENTS.

Valori restituiti

Returns an array indexed by keys. Each element is true if the corresponding key was deleted, or one of the Memcached::RES_* constants if the corresponding deletion failed.

The Memcached::getResultCode() will return the result code for the last executed delete operation, that is, the delete operation for the last element of keys.
