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.



Number of seconds to wait before invalidating the items.


Gibt bei Erfolg true zurück. Bei einem Fehler wird false zurückgegeben. Benutzen Sie wenn nötig Memcached::getResultCode().


Beispiel #1 Memcached::flush() example

= new Memcached();
$m->addServer('localhost', 11211);

/* flush all items in 10 seconds */
