Hey Mark,

I'm thinking of how PHP behaves. Arrays in PHP know the order that  
elements were added so that when you use foreach you get the elements  
in that same order. I always found this very useful when working with  
arrays in PHP.

For a little more info on what PHP does take a look at the comment by  
php_man_resp on the foreach page in the docs:

<http://www.php.net/foreach>

This is what I currently do and it works fine in many cases. But some  
things could be simplified if foreach iterated in the order keys were  
added.
