How to define an array in PHP

In PHP you can give a single definition to a variable. If you wanted to add a list of items to a variable, you would be creating an array. Below is how you create an array in PHP.

<?php 

// define an array

$WoWClasses = array('Druid', 'Shaman', 'Paladin', 'Hunter', 'Warrior', 'Death Knight', 'Priest', 'Mage', 'Warlock'); 

print_r($WoWClasses); 

?> 

In our example above, we can then print the contents of the array using print_r. Once we know how to create an array, we can then use loops to cycle though them using all of their contents.
