Memcached::flush
(PECL memcached >= 0.1.0)
Memcached::flush — Invalidate all items in the cache
Описание
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.
Список параметров
-
delay -
Number of seconds to wait before invalidating the items.
Возвращаемые значения
Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки.
Используйте при необходимости Memcached::getResultCode().
