What steps can be taken to troubleshoot PHP session issues after a server move?

One common issue after a server move is PHP session problems due to different server configurations. To troubleshoot this, make sure the session save path is writable, check if session cookies are being set correctly, and verify that session variables are being properly initialized and stored. 

// Check session save path
session_save_path('/path/to/writable/directory');

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

// Start the session
session_start();

// Initialize session variables
if (!isset($_SESSION['initialized'])) {
    session_regenerate_id();
    $_SESSION['initialized'] = true;
}
