Android Push Notifications using Google Cloud Messaging (GCM), PHP and MySQL Part - 2

In this tutorial i give the instruction from the previous post Android Push Notifications using Google Cloud Messaging (GCM), PHP and MySQL Part - 1 if you are new to this please go through my previous post.
 Now lets start the coding from the PART - 1

5. Create another file named GCM.php This file used to send push notification requests to GCM server.

GCM.php

<?php class GCM {     //put your code here     // constructor     function __construct() {               }     /**      * Sending Push Notification      */     public function send_notification($registatoin_ids, $message) {         // include config         include_once './config.php';         // Set POST variables         $url = 'https://android.googleapis.com/gcm/send';         $fields = array(             'registration_ids' => $registatoin_ids,             'data' => $message,         );         $headers = array(             'Authorization: key=' . GOOGLE_API_KEY,             'Content-Type: application/json'         );         // Open connection         $ch = curl_init();         // Set the url, number of POST vars, POST data         curl_setopt($ch, CURLOPT_URL, $url);         curl_setopt($ch, CURLOPT_POST, true);         curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);         curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);         // Disabling SSL Certificate support temporarly         curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);         curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));         // Execute post         $result = curl_exec($ch);         if ($result === FALSE) {             die('Curl failed: ' . curl_error($ch));         }         // Close connection         curl_close($ch);         echo $result;     } } ?>

6. Create a new file called register.php This file receives requests from android device and stores the user in the database.

register.php

<?php // response json $json = array(); /**  * Registering a user device  * Store reg id in users table  */ if (isset($_POST["name"]) && isset($_POST["email"]) && isset($_POST["regId"])) {     $name = $_POST["name"];     $email = $_POST["email"];     $gcm_regid = $_POST["regId"]; // GCM Registration ID     // Store user details in db     include_once './db_functions.php';     include_once './GCM.php';     $db = new DB_Functions();     $gcm = new GCM();     $res = $db->storeUser($name, $email, $gcm_regid);     $registatoin_ids = array($gcm_regid);     $message = array("product" => "shirt");     $result = $gcm->send_notification($registatoin_ids, $message);     echo $result; } else {     // user details missing } ?>

7. Create another file called send_message.php This file used to send pushnotification to android device by making a request to GCM server.

send_message.php

<?php if (isset($_GET["regId"]) && isset($_GET["message"])) {     $regId = $_GET["regId"];     $message = $_GET["message"];           include_once './GCM.php';           $gcm = new GCM();     $registatoin_ids = array($regId);     $message = array("price" => $message);     $result = $gcm->send_notification($registatoin_ids, $message);     echo $result; } ?>

In this post i conclude from this step i will continue this concept on later post...pls comment below...
