8. Array
Each item in an array is numbered starting from 0. For example, when we create an array:
<?php
$myArray = array("do", "re", "mi");
?>
Therefore, we can access a particular item of the array using its position, like this:
<?php
$myArray = array("do", "re", "mi");
echo $myArray[0]
// outputs "do"
?>
