    (PECL memcached >= 0.1.0)

    Memcached::flush — Invalidate all items in the cache

    Опис

    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.

    Параметри

    delay

    Number of seconds to wait before invalidating the items.

    Значення, що повертаються

    Повертає true у разі успіху або false в разі помилки. За необхідності використовується Memcached::getResultCode().

    Приклади
