class B extends A {    
    public function print_b() {
        return  'class B extends A' . "<br />";
    }

class C extends B {
    public function print_c() {
        return  'class C extends B' . "<br />";
    }
    public function print_all() {
        echo $this->print_a();
        echo $this-> print_b();
        echo $this->print_c();
