<!-- Let's create a new array called $users that have the following keys and values

$users['first_name'] = "Michael";
$users['last_name'] = "Choi";

Create a function where you can pass this $users and which would print an output that looks like below

There are 2 keys in this array: first_name, last_name
The value in the key 'first_name' is 'Michael'.
The value in the key 'last_name' is 'Choi'. -->


<?php
