What are the differences between the "me" and "id" methods in the Xing API when retrieving user data in PHP, and how should they be implemented in a PHP script like the one provided in the forum thread?

The main difference between the "me" and "id" methods in the Xing API when retrieving user data in PHP is that the "me" method is used to get the data of the currently authenticated user, while the "id" method is used to get the data of a specific user by their ID. To implement this in a PHP script, you can use the "me" method to retrieve the data of the authenticated user and the "id" method to retrieve the data of a specific user by passing their ID as a parameter.

// Get data of the currently authenticated user
$me_data = $xing->get('/users/me');

// Get data of a specific user by their ID
$user_id = '123456789';
$user_data = $xing->get('/users/' . $user_id);
