The PHP cache uses the monitoring test code.

The following code exists under the PHP Web site and is then accessed through IE browser.

#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

*/

function Size_for_humans ($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);
