How can you prevent session variables from being further passed on in PHP?

To prevent session variables from being further passed on in PHP, you can unset the session variables once they are no longer needed. This ensures that the sensitive data stored in session variables is not accessible beyond its intended use. 

// Start the session
session_start();

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

// Unset session variables when they are no longer needed
unset($_SESSION['username']);
