Memcached::delete

(PECL memcached >= 0.1.0)

Memcached::deleteDelete an item

Beschreibung

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

Memcached::delete() deletes the key from the server. The time parameter is the amount of time in seconds (or Unix time until which) the client wishes the server to refuse add and replace commands for this key. For this amount of time, the item is put into a delete queue, which means that it won't possible to retrieve it by the get command, but add and replace command with this key will also fail (the set command will succeed, however). After the time passes, the item is finally deleted from server memory. The parameter time defaults to 0 (which means that the item will be deleted immediately and further storage commands with this key will succeed).

Parameter-Liste

key

time

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

Rückgabewerte

Gibt bei Erfolg TRUE zurück. Im Fehlerfall wird FALSE zurückgegeben. 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.
