I use $file = $REQUEST_URI;
Probably the same variable. 

The easiest option is:
create a text file on the server (either using SCP or FTP) containing just:
<?php phpinfo(); ?>
(If that doesn't get through the filters, try this and swap the &lt; and &gt; 
for the normal tag angle brackets:
&lt;?php phpinfo(); ?&gt;
Now call the file phpinfo.php and load it into a browser from your local 
machine using the full http:// address.

That gives you an immense amount of information on PHP including ALL the 
environmental variables available so that you can get exactly the one you 
want - e.g. there are versions with or without the domain name or the http:// 
etc.

phpinfo() also reveals a LOT of sensitive info if you leave it on the server, 
so save the output as HTML on your local machine and delete the file from the 
server.

If you are in any doubt about the configuration of PHP on any server (to 
which you have FTP/SCP access) phpinfo() is always the quickest and best way 
to find out the info you need. Just always remember to delete it afterwards.
