I’m an android developer and currently working on GCM server side using PHP. From my client side I’m storing the gcm response token in one database, and now I want to send message to the registered users, at one go. I’m not able to figure out how to do that, and I’m totally confused. My simple HTML file is:

<html>
<head>
<title>
GCM
</title>
</head>
<body topmargin="50" leftmargin="50" CLASS = "bg">
<form action="send_message.php" name="myform" method="post">
<h4>Admin for sending notificaion to the registered user</h4>
Notification Text: <input name="appText" size="15" type="text"/><br>
URL: <input name="url" size="15" type="text" /><br>
<button type="submit">Submit</button>
</form>
</body>
</html>

And, my send_message.php:

<?php
error_reporting (0);

$link = mysql_connect("localhost","db","db"); 
if (!$link) 
 { 
 die(mysql_error()) ; 
 } 
mysql_select_db("gcm_user")or die(mysql_error());
........................................
.....................................
.....................................
?>

Now, in the php file what should I do, I have tried this link Android Hive example

But I want only one php for my purpose. Please help in overcoming this prm.

    Answering my own question. Here is what I have done to meet my requirements.

    $gcm_text = $_POST['gcmText'];
$gcm_url = $_POST['gcmURL'];
$gcm_subText = $_POST['gcm_secondText'];

$sql = "select gcm_response_token as regId from GCM";
$result = mysql_query($sql);

while ($row = mysql_fetch_assoc($result)) {
    $gcm_array[]=$row['regId'];
    $counter++;
}

mysql_free_result($result);


    $body['allsearch'] = array(
            'gcmText' => $gcm_text,
            'gcm_secondText' => $gcm_subText,
            'gcmURL' => $gcm_url
            );

    // Set POST variables
  $url = 'https://android.googleapis.com/gcm/send';

  $fields = array(
 'registration_ids' => $gcm_array,
 'data' => $body,
 );

//echo GOOGLE_API_KEY;
 $headers = array(
 'Authorization: key=$apiKey',
  'Content-Type: application/json'
 );


print_r($headers);
// 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;

?>

    By this, I was able to send json data to the client side and get the notification.
