sorry just a quick note I caught myself on...
inside the object you'd have to declare the variable... like so..
class Cart {
var $var;
function Cart() {
$this->var =& $GLOBALS['var'];
}
}
for php 5 you can use its "native" constructor __Construct() instead of
the shown example... which is for PHP < 5 :)
