What are some potential pitfalls when using sessions in PHP, especially on different devices?

One potential pitfall when using sessions in PHP on different devices is that the session data may not be shared between devices, leading to inconsistencies in user experience. To solve this, you can use session cookies with a consistent domain and path to ensure that the session data is accessible across different devices. 

// Set session cookie parameters for consistent domain and path
session_set_cookie_params(0, '/', '.example.com');
session_start();
