Subject: Private properties, Inheritance, Reflection (5.3)
From: r.borschel@gmx.net (Roman Borschel)

Hi,

i've got a little question that involves private properties, =20
inheritance and Reflection with PHP 5.3 RC1.

Given the following simple classes

class Foo {
     private $foo =3D 'value';
     public function getFoo() { return $this->foo; }
}
class Bar extends Foo {}

Obviously, given an instance of Bar, say $bar, $bar->getFoo() returns =20=

'value'.

Now the question: How do I get at this value using reflection, given =20
an instance of Bar?

$class =3D new \ReflectionClass('Foo');
$fooProp =3D $class->getProperty('foo');
$fooProp->setAccessible(true);
$bar =3D new Bar;
$value =3D $fooProp->getValue($bar);
var_dump($value); // NULL
var_dump($bar); // array(1) { ["=EF=BF=BDFoo=EF=BF=BDfoo"]=3D>  =
string(5) "value" }

How do I get at the value exposed by "var_dump($bar);" through =20
reflection?
Obviously, I can't upcast like this: "$fooProp->getValue((Foo)$bar)".

I'm asking here because I have the bad feeling that this is might not =20=

(yet?) be possible.

Thanks!
