What are some best practices for testing and verifying session functionality in a PHP script?

When testing and verifying session functionality in a PHP script, it is essential to ensure that sessions are being properly started, stored, and destroyed. One best practice is to test the session functionality by setting and retrieving session variables to confirm that they are being stored and retrieved correctly. Additionally, verifying that sessions are being destroyed when the user logs out or after a certain period of inactivity is crucial for security reasons. 

// Start the session
session_start();

// Set a session variable
$_SESSION['username'] = 'example_user';

// Retrieve the session variable
$username = $_SESSION['username'];

// Destroy the session
session_destroy();
