(PECL memcached >= 0.1.0)

Memcached::delete — Delete an item

설명

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).

인수

time

반환값

성공 시 TRUE를, 실패 시 FALSE를 반환합니다. The Memcached::getResultCode() will return Memcached::RES_NOTFOUND if the key does not exist.
