IP Address

Anyone know where or what I can do to a get a simple webpage that shows the ip address of the compter that is browsing it. Like http://www.whatismyip.com/

in PHP:

PHP Code:

---

<?
echo "Your IP is: " . $_SERVER['REMOTE_ADDR'];
?>

---

Damn I knew it was going to be easy, but not one line easy :rolleyes:

Thanks
