GCM отправляет сообщение на все устройства

У меня проблема с GCM, я не могу отправить сообщение на все устройства.

Это не оригинальный код, а моя собственная версия!

send_message.php:

<?php
if (isset($_POST["regId"]) && isset($_POST["message"])) {
//$regId = $_POST["regId"];
$message = $_POST["message"];

include './GCM.php';

$gcm = new GCM();

//$registatoin_ids = array($regId);
$message = array("price" => $message);include_once 'db_functions.php';

$db = new DB_Functions();
$users = $db->getAllUsers();

if($users != false){
$no_of_users = mysql_num_rows($users);
}else{
$no_of_users = 0;
}$i = 0;

while ($row = mysql_fetch_array($users)) {
$ids[$i] = $row["gcm_regid"];
$i++;

foreach ($ids as $value){
echo $value;
$registatoin_ids = $value;
json_encode($registatoin_ids);
$result = $gcm->send_notification($registatoin_ids, $message);
echo $result;
}
}

echo $value;
echo $registatoin_ids;
}
?>

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;
}
}
?>

db_functions.php:

<?php

class DB_Functions {

private $db;

//put your code here
// constructor
function __construct() {
include_once './db_connect.php';
// connecting to database
$this->db = new DB_Connect();
$this->db->connect();
}

// destructor
function __destruct() {

}

/**
* Storing new user
* returns user details
*/
public function storeUser($name, $email, $gcm_regid) {
// insert user into database
$result = mysql_query("INSERT INTO gcm_users(name, email, gcm_regid, created_at) VALUES('$name', '$email', '$gcm_regid', NOW())");
// check for successful store
if ($result) {
// get user details
$id = mysql_insert_id(); // last inserted id
$result = mysql_query("SELECT * FROM gcm_users WHERE id = $id") or die(mysql_error());
// return user details
if (mysql_num_rows($result) > 0) {
return mysql_fetch_array($result);
} else {
return false;
}
} else {
return false;
}
}

/**
* Get user by email and password
*/
public function getUserByEmail($email) {
$result = mysql_query("SELECT * FROM gcm_users WHERE email = '$email' LIMIT 1");
return $result;
}

/**
* Getting all users
*/
public function getAllUsers() {
$result = mysql_query("select * FROM gcm_users");
return $result;
}

/**
* Check user is existed or not
*/
public function isUserExisted($email) {
$result = mysql_query("SELECT email from gcm_users WHERE email = '$email'");
$no_of_rows = mysql_num_rows($result);
if ($no_of_rows > 0) {
// user existed
return true;
} else {
// user not existed
return false;
}
}

}

?>
