Are there any best practices for handling session management in PHP applications to avoid unexpected session termination?

Session management in PHP applications can be improved by setting appropriate session configuration options, such as session.gc_maxlifetime and session.cookie_lifetime, to ensure sessions do not expire unexpectedly. Additionally, developers should regenerate session IDs periodically to prevent session fixation attacks and implement proper error handling to gracefully handle session expiration. 

// Set session configuration options
ini_set('session.gc_maxlifetime', 3600); // Session expires after 1 hour of inactivity
ini_set('session.cookie_lifetime', 0); // Session cookie expires when the browser is closed

// Regenerate session ID periodically
if (isset($_SESSION['last_activity']) && time() - $_SESSION['last_activity'] > 1800) { // Regenerate every 30 minutes
    session_regenerate_id(true);
}

// Handle session expiration gracefully
if (isset($_SESSION['last_activity']) && time() - $_SESSION['last_activity'] > ini_get('session.gc_maxlifetime')) {
    session_unset();
    session_destroy();
}
