Memcached::flush — Invalidate all items in the cache
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.
delayNumber of seconds to wait before invalidating the items.
Restituisce true in caso di successo, false in caso di fallimento.
Utilizzare Memcached:getResultCode() se necessario.
Example #1 Memcached::flush() example
<?php
$m = new Memcached();
$m->addServer('localhost', 11211);
/* flush all items in 10 seconds */
$m->flush(10);
