Cycling through arrays without looping through it

array_cycle.php

<?php 

/*
I was faced with a problem where I had to cycle through a list of HTML colors and I thought this was 
a nice way of doing it. As array_shift returns the value you remove at the front, simply appending it
to the array does the business. I thought I would share it in-case someone finds it useful.
