What are the potential benefits of passing variables between PHP files using Sessions?

Passing variables between PHP files using Sessions allows for the sharing of data across different pages within a website or web application. This can be useful for maintaining user login information, shopping cart contents, and other important data throughout a user's session. Sessions provide a way to store and retrieve variables that are accessible across multiple pages without the need to constantly pass them through URLs or forms. 

// Start the session
session_start();

// Set a variable in one PHP file
$_SESSION['username'] = 'JohnDoe';

// Retrieve the variable in another PHP file
$username = $_SESSION['username'];

// Output the variable
echo $username;
