What are common issues with PHP sessions when migrating to a new server?

Common issues with PHP sessions when migrating to a new server include session data not persisting, session variables being lost, or session timeouts not working correctly. To solve these issues, make sure the session save path is writable on the new server, ensure the session cookie parameters are set correctly, and check if the session handler is configured properly. 

// Set the session save path to a writable directory
session_save_path('/path/to/writable/directory');

// Set session cookie parameters
session_set_cookie_params(0, '/', '.yourdomain.com', true, true);

// Configure session handler (if needed)
// Example using database handler
ini_set('session.save_handler', 'user');
ini_set('session.save_path', 'tcp://localhost:11211');
