Memcached::flush

(PECL memcached >= 0.1.0)

Memcached::flush — Invalidate all items in the cache

Описание

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

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.

Список параметров

delay: Numer of seconds to wait before invalidating the items.

Возвращаемые значения

Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки. Используйте при необходимости Memcached::getResultCode().
