How to make a "Server too busy to handle your request" in PHP?

Right now I don't have time to optimize and to upgrade servers and once or twice a month the server reaches critical load (mysql basically) and it goes very very slow.

I want to show a static message saying the server is too busy when that happens.

How would I do that?

Solution

  • There's a function for that: http://www.php.net/manual/en/function.sys-getloadavg.php

    example usage:

    <?php
$maxLoad = 10;
$load = sys_getloadavg();
if ($load[0] > $maxLoad) {
    header('HTTP/1.1 503 Too busy, try again later');
    die('Server too busy. Please try again later.');
}else{
    show_my_page();
}
