php 缓存使用监控测试代码。

将以下代码存在PHP WEB网站下面，然后通过IE浏览器进行访问。

#cat ocpcache.php

<?php

/*

* Fetch configuration and status information from OpCache

*/

$config = opcache_get_configuration();

$status = opcache_get_status();

/*

* Turn bytes into a human readable format

* @param $bytes

*/

    if ($bytes > 1048576) {

        return sprintf("%.2f&nbsp;MB", $bytes/1048576);

    } else if ($bytes > 1024) {

        return sprintf("%.2f&nbsp;kB", $bytes/1024);

    } else return sprintf("%d&nbsp;bytes", $bytes);

}
