Memcached::flush

(PECL memcached >= 0.1.0)

Memcached::flush — Invalidate all items in the cache

Beschreibung

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.

Parameter-Liste

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

Rückgabewerte

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

Beispiele

Beispiel #1 Memcached::flush() example

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

/* flush all items in 10 seconds */
$m->flush(10);
?>
