Android GCM send multiple message to device - php

Question

I kinda stuck on a problem. I need to send message notification and alert notification to the device. Message notification is sent when a user send message to other and alert notification is generated to alert user from server. That mean I need multiple notification types. I am using this on my server to push notification to my device.
// This is code from the class that take user input
$notify = "This is message"
$msg = array("Message" => $notify);
$sense = $gcm->send_notification($registatoin_ids, $msg);
//This is the send notification in GCM class
public function send_notification($registatoin_ids, $message) {
// 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;
}
How can I adjust the above code to meet my requirement. I tried by sending
$fields = array(
"registration_ids" : registatoin_ids,
"data" : {
"type" : "Message",
"Message" : $message,
}
);
But I got error as
E/JSON(3444): <b>Parse error</b>: syntax error, unexpected ':', expecting ')' in <b>/home/a8709494/public_html/mobile/GCM.php</b> on line <b>25</b><br />

Answer 1

You need to use the => operator for this:
$fields = array(
"registration_ids" => "registatoin_ids",
"data" => array(
"type" => "Message",
"Message" => $message,
)
);
