Re: [PHP] Inheritance and a class function: on what class was it called?

[Debbie Dyer]

I think I know what you mean. You could get it to return the name of the
class.

eg.

class A {
    function foo () {
      return get_class($this);
    }
}
class B extends A {
}
class C extends A {
}

  $a = new A();
  $b = new B();
  $c = new C();
  print $a->foo();
  print $b->foo();
  print $c->foo();

Is this what you mean?
