Sorry, I'm just not in the mood for a lesson on data structures, ordered
maps, and object iterators. It'd take a couple of hours.

However:

Stop thinking of PHP arrays as C arrays. PHP arrays are ordered maps. They
don't even have to have integer indexes.

Do read the PHP manual on arrays, the foreach() construct and object
iterators.

Grab a C/C++ book which covers the STL library, so you can see the
differences between a vector, an array, a map, a hash table, and an ordered
hash table.
