i am using following code to send gcm message using php and mysqldb i have successfully send the gcm message and received it on the device however the android guidelines state that gcm message should be send in batch of 1000 each http://developer.android.com/training/cloudsync/gcm.html#multicast
now my question is how can we send gcm messages in lots of 1000 to a database of say 10,000 registered users.
<?php
require 'connect.php';
function sendPushNotification($registration_ids, $message) {
$url = 'https://android.googleapis.com/gcm/send';
$fields = array(
'registration_ids' => $registration_ids,
'data' => $message,
);
define('GOOGLE_API_KEY', 'keys_value');
$headers = array(
'Authorization:key=' . GOOGLE_API_KEY,
'Content-Type: application/json'
);
echo json_encode($fields);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
$result = curl_exec($ch);
if($result === false)
die('Curl failed ' . curl_error());
curl_close($ch);
return $result;
}
$pushStatus = '';
if(!empty($_GET['push'])) {
$query = "SELECT gcm_regId FROM gcm_users";
if($query_run = mysql_query($query)) {
$gcmRegIds = array();
while($query_row = mysql_fetch_assoc($query_run)) {
array_push($gcmRegIds, $query_row['gcm_regId']);
}
}
$pushMessage = $_POST['message'];
if(isset($gcmRegIds) && isset($pushMessage)) {
$message = array('price' => $pushMessage);
$pushStatus = sendPushNotification($gcmRegIds, $message);
}
}
?>
