Memcached::flush
Memcached::flush
(PECL memcached >= 0.1.0)
Memcached::flush — Invalidate all items in the cache
Description
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.
Parameters
-
delay -
Number of seconds to wait before invalidating the items.
Return Values
Returns TRUE on success or FALSE on failure. Use Memcached::getResultCode() if necessary.
Examples
Example #1 Memcached::flush() example
<?php
$m = new Memcached();
$m->addServer('localhost', 11211);
/* flush all items in 10 seconds */
$m->flush(10);
?>
