Hello,

This code isn't work under PHP4:
<?
class Cart {
    var $items;
    function add_item($num) {
        $this->items += $num;
    }
    function get_items() {
      return $this->items;
    }
}

$nnn = new Cart;
$nnn->add_item(10);
list($itm) = $nnn->get_items();
echo "Items: $itm<br>";

$nnn->add_item(100);
list($itm) = $nnn->get_items();
echo "Items: $itm<br>";
?>

I have nothing on output here
