Get the full URL in PHP

Have a look at $_SERVER['REQUEST_URI'], i.e.

$actual_link = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";

(Note that the double quoted string syntax is perfectly correct)

Editor's note: using this code has security implications. The client can set HTTP_HOST to any arbitrary value it wants.
