Limiting access to web-pages by IP-address with PHP

We need to limit access to a group of our web-pages. We use MODx CMS and it seems that the most simple way to do accomplish what we want would be to have a small PHP-script that gets executed from the HTML-templates and checks the IP-address of the user. So far all the instructions we've found from the internet deal with configuring the web-server, which in our case is not a viable option. Could anyone point us to the right direction with limiting access with php? Thanks!

$_SERVER['REMOTE_ADDR'] may be of some use

Perfect! Here's what I ended up doing:

<?php
if (preg_match("/^xxx\.xxx\./", $_SERVER['REMOTE_ADDR'])) {
header("location: our_error_page");
exit();
}
?>

I first did it by writing refresh meta to the document with echo if the beginning of the IP-address doesn't match the regex, but that caused the page to quickly flash on screen before the refresh took place. Header is much better.

Thanks guys!
