PHP google analytics Tracking across multiple domains - php

Question

How to track the movement of the user between the two domains?
scheme:
1) the user clicks the button in doman-exemple1.com and go out from doman-exemple1.com and comes to doman-exemple2.com
login
2) doman-exemple2.com executed only on the server (that is not possible to use javascript)
<?php
// executed something codes... ;
// go with result to doman-exemple1.com
header('Location: http://doman-exemple1.com/?good='.$code);
?>
3) user returned to the http://doman-exemple1.com/?good=t45ygsw45t4
I need that google analytics understand that this same user and it not different users
This works:

But I cannot use thit becouse doman-exemple2.com executed only PHP and cannot use javascript
please help how to do this without javascript and only with PHP
P.S.
I read this: https://github.com/thomasbachem/php-ga but not understand if i can use this in my situations

Answer 1

If you are using Universal Analytics of GA, then have a look at the Measurement Protocol.
https://developers.google.com/analytics/devguides/collection/protocol/v1/devguide
That can allow you to track through PHP only, and by using the same cid you can continue to track (using the same profile) the session.

code get from this example: http://www.stumiller.me/implementing-google-analytics-measurement-protocol-in-php-and-wordpress/
