How can I integrate the new Google Cloud Messaging in a PHP backend?
This code will send a GCM message to multiple registration IDs via PHP CURL.
// Payload data you want to send to Android device(s)
// (it will be accessible via intent extras)
$data = array('message' => 'Hello World!');
// The recipient registration tokens for this notification
// https://developer.android.com/google/gcm/
$ids = array('abc', 'def');
// Send push notification via Google Cloud Messaging
sendPushNotification($data, $ids);
function sendPushNotification($data, $ids) {
// Insert real GCM API key from the Google APIs Console
// https://code.google.com/apis/console/
$apiKey = 'abc';
// Set POST request body
$post = array(
'registration_ids' => $ids,
'data' => $data,
);
// Set CURL request headers
$headers = array(
'Authorization: key=' . $apiKey,
'Content-Type: application/json'
);
// Initialize curl handle
$ch = curl_init();
// Set URL to GCM push endpoint
curl_setopt($ch, CURLOPT_URL, 'https://gcm-http.googleapis.com/gcm/send');
// Set request method to POST
curl_setopt($ch, CURLOPT_POST, true);
// Set custom request headers
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
// Get the response back as string instead of printing it
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Set JSON post data
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($post));
// Actually send the request
$result = curl_exec($ch);
// Handle errors
if (curl_errno($ch)) {
echo 'GCM error: ' . curl_error($ch);
}
// Close curl handle
curl_close($ch);
// Debug GCM response
echo $result;
}
