PHP-Handbuch: Invalidate all items in the cache

Beschreibung

public bool Memcached::flush ([ int $delay = 0 ] )

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.

Parameter-Liste

delay: Number of seconds to wait before invalidating the items.

Rückgabewerte

Gibt bei Erfolg TRUE zurück. Im Fehlerfall wird FALSE zurückgegeben. Benutzen Sie wenn nötig Memcached::getResultCode.

Beispiele

Beispiel #1 Memcached::flush example


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

$m->flush(10);
?>
