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

* Fetch configuration and status information from OpCache

$config = opcache_get_configuration();

$status = opcache_get_status();

* Turn bytes into a human readable format

* @param $bytes

function size_for_humans($bytes) {

if ($bytes > 1048576) {

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

} else if ($bytes > 1024) {

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

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

}
