What is the purpose of using array_values() in PHP and how is it relevant to session variables?

The purpose of using array_values() in PHP is to reset the keys of an array to be numerical and starting from 0. This can be useful when you want to reindex an array that has non-sequential keys. When dealing with session variables, using array_values() can be relevant when you want to retrieve the values stored in the session as a numerically indexed array. 

// Example of using array_values() with session variables
session_start();

// Assume we have session variables stored in $_SESSION['data']
$data = $_SESSION['data'];

// Reset the keys of the array to be numerical
$data = array_values($data);

// Now $data will be a numerically indexed array
