PHP Error: "Call to undefined function AddUser() ". What am I doing wrong?

Question

Code: http://pastebin.com/h8WuYbJn
Full error:
Fatal error: Call to undefined function AddUser() in C:\xampp\htdocs\scripts\steam.php on line 37

What exactly am I doing wrong? Everything should be right, but it isn't (at least according to PHP).

You don't use the . in PHP. Use -> instead, eg:

$x->AddUser('FakeId','FakeUser');
$x->Refresh('FakeUser');

The . is PHP's concatenation operator, so it thinks you want

$x . AddUser('FakeId', 'FakeUser'); // $x concatenated with AddUser(...)

And of course Adduser() is undefined.
