I have been playing with PHP5 and am liking it more and more. But I have one
question about "instanceof"

If you have something like this:

<?
class A { }
class B extends A { }
$x = new B;
if ($x instanceof B)  echo "B";
if ($x instanceof A)  echo "A";
?>

This would echo "BA". That's good, I understand that.

Now the question: Is it possible to determine if B is an instance of A
without instantiating it?

Thanks
Martin
