What are the advantages of using sessions over hidden fields in PHP form handling to prevent manipulation by users?

Using sessions over hidden fields in PHP form handling helps prevent manipulation by users because session data is stored on the server-side, making it more secure than hidden fields which are stored on the client-side and can be easily manipulated by users. Sessions also provide a convenient way to store and retrieve data across multiple pages without exposing sensitive information to users. 

<?php
session_start();

// Set session data
$_SESSION['username'] = 'john_doe';

// Retrieve session data
$username = $_SESSION['username'];

// Destroy session data
session_destroy();
?>
