Answer 1

array is one the eight primitive types in PHP. Allthough it comes with a lot of built-in utility functions, but they are all procedural.

Both the ArrayObject and the ArrayIterator allow us to make arrays first class citizens in an object oriented program (OOP).

Difference between ArrayObject and the ArrayIterator is that, since ArrayIterator implements SeekableIterator interface, you can do $myArray->seek(10); with ArrayIterator.
