Well, the scope of the $server, $username, $password variables is the
class. You can only use these variables in the class 'calling' them
with the $this->server. So, your connect won't work since it doesn't
call the variables with $this. The $handle is available only for that
method (function). If you want to use it, as wade said, use return.
