What is the difference between destroying a session and logging out in PHP?

Destroying a session in PHP involves completely removing all session data, while logging out typically involves ending the current session without removing the session data. When destroying a session, all session variables are removed and the session ID is invalidated. Logging out usually involves simply unsetting the user's authentication status and possibly clearing specific session variables related to the user's login status. 

// Destroying a session
session_start();
session_unset();
session_destroy();

// Logging out
session_start();
unset($_SESSION['user_id']);
// Additional logout logic can be added here
