innanzitutto installare Apache2, seguendo le istruzioni di questo sito:
ricordiamoci che per il nostro esempio bisogna anche installare Curl, con il seguente comando sempre via terminale:
sudo apt-get install php5-curl
Quindi creiamo un file PHP nella nostra cartella (quella di base dovrebbe essere /var/www/ ) e lo nominiamo gcm.php
<?php
//Generic php function to send GCM push notification
function sendMessageThroughGCM($registatoin_ids, $message) {
//Google cloud messaging GCM-API url
$url = 'https://android.googleapis.com/gcm/send';
$fields = array(
'registration_ids' => $registatoin_ids,
'data' => $message,
);
// Update your Google Cloud Messaging API Key
define("GOOGLE_API_KEY", "InserisciQuiLaTuaServerKey");
$headers = array(
'Authorization: key=' . GOOGLE_API_KEY,

Nella stessa cartella dovrà esservi un file Id.txt dove dentro vi sarà scritto la key del device autorizzato...
