Maybe I'm wrong, but I thought you couldn't use the "$f->foo" to access private variables from outside a class?

I think he means: echo $f->__get('foo'); $f->__set('foo', 'bar'); echo $f->__get('foo');

no, he doesn't. http://www.php.net/manual/en/language.oop5.magic.php should explain it, however the part about __get() and __set() isn't quite finished yet (and thus missing). Rest assured though, Jochem showed a correct way of handling this "problem", though PHP had a bug relating to recursive lookups when using isset() in combination with __get().
