An associative array also stores data in the same way but gives you more flexibility by letting you assign any name you want to your keys instead of using keys 0, 1, 2, 3, 4, and so on. This is helpful when you want to assign a certain value to your key.

For example, you want an array which display the height of school children in cm, your associative array function will look like this:

<?php
$height=array('Billy'=>90, 'Sam'=>95, 'Susie'=>92, Tamara=>89);
?>

To retrieve the value for each key you just have to type in:
echo $height ('Billy'); or
echo $height ('Sam'); and so on.

Hope this helps.
