Google API PHP Client - Firebase Cloud Messaging Service v1 example
<?php
/**
* This serves as an example of how to use the Google API PHP Client
* with Firebase Cloud Messaging Service.
*
* The client can be found here:
* https://github.com/google/google-api-php-client
*
* At the time of writing this, there's no Service object for the correct
* scope for Firebase Messaging, so here's an example of how this can be
* done with provididing the scope manually.
*
* Info regarding authorization and requests can be found here:
* https://firebase.google.com/docs/cloud-messaging/server
