Why can I not get session variables from functions within classes?

The function only has access to locally defined variables and 
parameters passed in.  It therefore creates a new empty variable when 
you are really trying to access a session variable that is already 
defined. 
I usually do this:
function print_x() {
    global $x;// $x is your session variable, now you can use it
    print ($x);
}
