What are the potential pitfalls of relying on automatic cookie management for Session-IDs in PHP?

Potential pitfalls of relying on automatic cookie management for Session-IDs in PHP include security vulnerabilities such as session fixation attacks and session hijacking. To mitigate these risks, it is recommended to regenerate the Session-ID periodically or upon certain events to prevent attackers from predicting or stealing active sessions. 

// Regenerate Session-ID periodically or upon certain events
if (isset($_SESSION['last_regenerated']) && time() - $_SESSION['last_regenerated'] > 1800) {
    session_regenerate_id(true);
    $_SESSION['last_regenerated'] = time();
}
