Private properties, Inheritance, Reflection (5.3)

Hi, i've got a little question that involves private properties, inheritance and Reflection with PHP 5.3 RC1. Given the following simple classes class Foo {

    private $foo = 'value';
    public function getFoo() { return $this->foo; }

} class Bar extends Foo {} Obviously, given an instance of Bar, say $bar, $bar->getFoo() returns 'value'. Now the question: How do I get at this value using reflection, given an instance of Bar? $class = new \ReflectionClass('Foo'); $fooProp = $class->getProperty('foo'); $fooProp->setAccessible(true); $bar = new Bar; $value = $fooProp->getValue($bar); var_dump($value); // NULL var_dump($bar); // array(1) { ["�Foo�foo"]=> string(5) "value" } How do I get at the value exposed by "var_dump($bar);" through reflection? Obviously, I can't upcast like this: "$fooProp->getValue((Foo)$bar)". I'm asking here because I have the bad feeling that this is might not (yet?) be possible. Thanks! Roman
