You should be using $_SERVER (for PHP4 and up). Other than that, I know exactly what you mean

Yea thats one of the things that changed from PHP3 to PHP4. I had forgotten all about it. I just used this in my video app that was assigning an incorrect URL to videos. This variable made the correction. Thanks.

This is fun, and very useful:

if ($_SERVER['HTTP_REFERER']=$_SERVER["HTTP_HOST"] . $_SERVER["REQUEST_URI"])
{echo 'Form came from me';}
else
{echo 'Form came from spam bot at'.$_SERVER['REMOTE_ADDR'].'.';}

What is the use of the ff codes?

if ($_SERVER['HTTP_REFERER']=$_SERVER["HTTP_HOST"] . $_SERVER["REQUEST_URI"])
{echo 'Form came from me';}
else
{echo 'Form came from spam bot at'.$_SERVER['REMOTE_ADDR'].'.';}

Yea, $.SERVER has a lot of other useful elements too.

These in particular for getting the complete current URL:
SERVER_PROTOCOL
HTTPS
SERVER_PORT
