An array's functionality can be implemented as a Class with specific
array instances being Objects. This allows the array to be used in
polymorphic contexts and to be extended by subclasses. The same can be
said for any primitive datatype.
Personally, I haven't seen a need to use an Array class in PHP. That's
not to say it doesn't have a purpose, but I lean towards primitives when
possible for efficiency.
