(PECL yac >= 1.0.0)
Yac::flush — Flush the cache
Removes all cached values. Because the cache is shared by every process of the same machine, this empties the cache globally; the key prefix given to Yac::__construct() does not limit what gets flushed.
この関数にはパラメータはありません。
Returns true.
例1 Yac::flush() example
<?php
$yac = new Yac();
$yac->set("foo", "bar");
$other = new Yac("app2_");
$other->set("baz", "qux");
// flush empties the whole cache: entries of every instance,
// regardless of the prefix used when they were stored
$yac->flush();
var_dump($yac->get("foo")); // bool(false)
var_dump($other->get("baz")); // bool(false)
?>
