Check the Referer to validate access

[Mr_C4]

How can I use PHP to validate that the page is being refered from a page in my site? I want to check to make sure the HTTP_REFERER variable has "www.abc.com" in it, and if NOT the say "Access Denied!" and STOP all other processing of the page, otherwise display the page as normal.

Any help would be appreciated, as I am very new to PHP, and couldn't even sucessfully "ECHO" the HTTP_REFERRER variable...

this code as the very first line (after <?php) should do the trick nicely 🙂

if (substr_count(getenv("HTTP_REFERER"),"www.abc.com") != 1)
    exit;

Hope that helps
