vBulletin and php_include protection, how to?

I'm just installing and everything went great, connections to db, gen setup, products, all work just fine. vbplugin/amember htpasswd works with that lovely grey box. Love that I was able to do all of this myself in no time, but I'm stumped now

I have no idea where to put this code in vBulletin (see below). i read both forums (amember, vbulletin) found some mention of php include template, where is that? how to?
Sorry, I'm not a php girl. Wish I could use new_rewrite but (RewriteRule doesn't work in .htaccess files on this server) so I'm waiting for support form ISP in the hopes they allow this module. would love use php_include for now.

-------------------------------------------here's the code
This method of protection is simple - your must edit your PHP files and include to TOP of each PHP file (or just into one which is included by all other files) these lines of code:

<?php
$_product_id = array(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24);
require_once '/providedbyprog/providedbyprog/providedbyprog/amember/plugins/protect/php_include/check.inc.php';
?>

what to do with all those lovely letters and numbers up there, hmmmm ?


any help would be so greatly appreciated
cheers,
