Let's say I have a page at another site that links to a php script on my server. Is there anyway to get the referrer to the php script using php?
Yes, and more. <?php echo "<pre>",print_r($_SERVER),"</pre>"; why are you echoing the result of print_r ?! The result is a boolean true or false. the actual output ON SCREEN is done from WITHIN the function automatically. Echoing the result is useless, and even more, it adds to confusion because of a '1' appearing all of a sudden on screen.
