Re: PHP5 - instanceof

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

Hi Martin, Reflection is your friend. <?php class A { } class B extends A { } $x = new Reflection_Class('B'); print_r($x); ?> Greg -- phpDocumentor http://www.phpdoc.org
