Memcached::delete — Delete an item

Descrizione

public Memcached::delete(string $key, int $time = 0): bool

Delete the key from the server.

Elenco dei parametri

key: The key to be deleted.
time: The amount of time the server will wait to delete the item.

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

Restituisce true in caso di successo, false in caso di fallimento. The Memcached::getResultCode() will return Memcached::RES_NOTFOUND if the key does not exist.

--For PECL memcached 2.10--
delete used with second argument 'time' returns false and set the error code and message for invalid arguments unless used without Memcached::OPT_BINARY_PROTOCOL.

getResultCode() and getResultMessage() returns  38 and INVALID ARGUMENTS respectively.
