Memcached::flushInvalidate all items in the cache


public Memcached::flush(int $delay = 0): bool

Memcached::flush() invalidates all existing cache items immediately (by default) or after the delay specified. After invalidation none of the items will be returned in response to a retrieval command (unless it's stored again under the same key after Memcached::flush() has invalidated the items). The flush does not actually free all the memory taken up by the existing items; that will happen gradually as new items are stored.

Bağımsız Değişkenler


Number of seconds to wait before invalidating the items.

Dönen Değerler

Başarı durumunda true, başarısızlık durumunda false döner. Gerekirse Memcached::getResultCode() kullanılmalıdır.
