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().
