PHP: Get A Random Item From An Array

In PHP it’s easy to work with arrays. Just declare someting like this:

<!--?php
$arrX = array("Kay", "Joe","Susan", "Frank");
?-->

Now you can access the values with their index (which starts a 0 for the first item).

<!--?php
// output "Kay"
echo $arrX[0];
 
// output "Susan"
echo $arrX[2];
?-->

PHP offers you several ways to get a random value of the array. One simple way is by using the array_rand() function. array_rand() expects the array as a parameter and returns a random index value as integer which then can be used to get the array value.
