TalkPHP - XBL Gamercard Fetching Class

Found this at simes.org. It's a class for fetching Xbox Live Gamertags. Pretty neat. I haven't looked through the entire code yet to see if there's stuff that needs to be fixed, etc. I'm new to OOP in PHP5, but this looks like it was written for PHP4. Someone correct me if I'm wrong. Enjoy.
PHP Code:

    var $tag;

    var $rep;
