[PHP] Page Generation Time

This is a cool script that will help you see the number of seconds needed to load your pages.

/* This part of the script goes at the top of your page */

$starttime = explode(' ', microtime());
$starttime = $starttime[1] + $starttime[0];

/* This part of the script goes where you want load time to be displayed */

$mtime = explode(' ', microtime());
$totaltime = $mtime[0] + $mtime[1] - $starttime;
printf('Page loaded in %.3f seconds.', $totaltime);
