In the provided PHP code, what improvements can be made to enhance security and efficiency, especially regarding session handling?

Issue: The provided PHP code does not use secure session handling practices, such as properly setting session cookie parameters, using HTTPS, and implementing session regeneration to prevent session fixation attacks. To enhance security and efficiency, these improvements should be implemented. 

// Improvements for secure session handling
// Set session cookie parameters for better security
session_set_cookie_params([
    'lifetime' => 0,
    'path' => '/',
    'domain' => 'example.com',
    'secure' => true,
    'httponly' => true,
    'samesite' => 'Strict'
]);

// Start session with improved cookie parameters
session_start();

// Regenerate session ID to prevent session fixation attacks
session_regenerate_id(true);
