& is used to create references -- kind of like \ in perl.
The above notation is unnecessary when developing in PHP5, as objects in
PHP5 are passed by reference by default. However, in PHP4, this was
often necessary if you needed to, for instance, store an object in an
array or another object (otherwise you got a copy of the object, which
means state would then differ between the original and the copy).
