What are common reasons for PHP sessions to stop working after a server migration?

Common reasons for PHP sessions to stop working after a server migration include changes in server configurations, session save path not being set correctly, or session data being lost during the migration process. To solve this issue, you can try setting the session save path explicitly in your PHP code to ensure sessions are stored in the correct location. 

<?php
session_save_path('/path/to/session/directory');
session_start();
?>
