how to do this with class?

Hello i've 2 class : class TC1 {

        var $a = "A";

}; class TC2 {

        var $parent;

        function TC2($p) {
                $this->parent=$p;
                }
        };

c1 = new TC1; c2 = nex TC2($c2); and i will to show $c1->a using $c2 i've tried : echo "$c2->parent->a"; but it doesn't works. i've to use another variable, like this : $aparent=$c2->parent; echo "$aparent->a"; how to do show variable a when calling directly class TC2?
