Memcached::flush

(PECL memcached >= 0.1.0)

Memcached::flushInvalidate all items in the cache

설명

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

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.

인수

delay

Numer of seconds to wait before invalidating the items.

반환값

성공할 경우 TRUE를, 실패할 경우 FALSE를 반환합니다. 필요할 경우 Memcached::getResultCode 사용.
