What role does the "automatically log in" checkbox play in PHP forums like My Little Forum, and how does it affect session management and user experience?

Issue: The "automatically log in" checkbox in PHP forums like My Little Forum allows users to stay logged in even after closing the browser. This affects session management by extending the session lifetime and can enhance user experience by providing convenience. PHP Code Snippet:

// Check if the "automatically log in" checkbox is selected
if(isset($_POST['remember_me'])) {
    // Extend the session lifetime to 30 days
    session_set_cookie_params(30 * 24 * 60 * 60);
} else {
    // Default session lifetime (until browser is closed)
    session_set_cookie_params(0);
}

// Start the session
session_start();
