signature help

[emin3m]

take a look at my current signature (its counter strike thingy )
am showing the user ip now
but i want to display the login name from which he has logged in to the forums,,, ofcourse by parsing
if hez logged in he views his name else his ip (owned both way )
problem is whn i use

$contents = file_get_contents("http://www.webdeveloper.com/forum/");
echo $contents;
exit(); 

it shows me that am not logged in but i juss am still logged in and if i open http://www.webdeveloper.com/forum/ in blank browser page it showss me logged in..
i figured out the problem was root and directory address was change of where this emzsig.php is uploaded.. i tried to use the chdir() and chroot()
chdir() works but chroot() dosent cz of am using free hosting with subdomain

and i want to ask if there is any free php enabled hosting which can let me achieve this goal or i still cant do this even i pay for domain ( HhMm i can use one of my software house's client domains )
or or any alternate way to do this same thing

laterz
