Hehe, my soul is hard to please...=P
Actually, __get() does work from inside the class. In the sample code I
posted, func() does indeed return 'x' when called from main. It does not
work when called from within a call to __get(). In other words,
$this->attribute does not work if __get() appears anywhere in the call
stack.
Its just a small annoyance. I use $this->attribute everywhere in the class,
but I have to remember to use $this->__get(attribute) in methods that can
be called from __get().
