Memcached::flush

(PECL memcached >= 0.1.0)

Memcached::flush — Invalidate all items in the cache

Description

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.
