Get URL of calling webpage in PHP

Question

I am working on a website statistics engine for a class. The idea being that you can simply embed a little code in your web page which will call the stats website on every p

Answer 1

In addition to $_SERVER['HTTP_REFERER'] since there may be large chunks of the URI you wish to ignore, you can just pass the page name as a request param to the called script.

I.E. on the page with stats tracking you request

URL/stats_tracker.php?page=checkout

on the stats tracker page you just look for

$_REQUEST['page'];

This can be cleaner than looking at the whole URL.
