The problem is that arrays are values in PHP. So when you return an
array from a function (or assign it to variable) you're really
returing/assigning a copy of the array.

This line adds "Mr Smith" to a copy of the authors array (as returned
by the __get function) and not the original array.
Your best bet is to use an ArrayObject rather than an array. It works
just like an array but, like all objects in PHP5, it's passed by
reference and should work as you expect.
