Are there any specific PHP configurations that need to be adjusted in order to enable automatic session ID passing in links?

To enable automatic session ID passing in links in PHP, you need to adjust the `session.use_trans_sid` configuration to `1`. This will allow PHP to automatically append the session ID to links. Additionally, make sure that `session.auto_start` is set to `1` to automatically start a session when a script starts.

<?php
ini_set('session.use_trans_sid', 1);
ini_set('session.auto_start', 1);
?>
