Instantiating class, classname in constant

Hi Fella's, Some of you might or might not remember me. I've been here before and I am here again. Hoping to stick around, ask, wonder and help a lot. So much for a starter. Now, aren't all of you as excited about php5 as I am? What a great change to the object model. Especially, .. well, basically all modifications are as good as all of the others. There's only one thing I can't seem to get working - not after googling, trying, searching, reading. Not even after just trying everything I thought to be reasonable. It's the following: <?php class Foo { const Bar = 'Foo_Bar'; const Chocolate = 'Foo_Chocolate'; const Target = 'Foo Target'; } $bar = new Foo::Bar(); ?> even though <?php $bar = Foo::Bar; $bar = new $bar(); ?> does instantiate an object of class Foo_Bar; After all this time I've given up on it, please ow please just tell me why it's not working. Same thing, btw, doesn't work for $obj = new __CLASS__(); or any object instantiation where the classname should come from something else then a regular, scalar variable. Any discussion on the item would be great, Wouter -- Always consider all options before deciding which object to talk to
