Given the following simple classes class Foo {

class Foo { private $foo = "value"; } class Bar extends Foo {} $f = new Foo; // we have to know the context, as there might be multiple foo properties $r = new ReflectionProperty("Foo", "foo"); $r->setAccessible(true); var_dump($r->getValue($f)); works for me. johannes

Thanks for your answer. Yes, this works, but here $f is an instance of Foo, not Bar. When you make it an instance of Bar you get NULL. I think this is not correct, is it? Given that we have a ReflectionProperty of class Foo at hand, from my understanding it should look at an instance of Bar as a Foo and return the value. Am I missing something? Regards Roman
