// API access key from Google API's Console
define( 'API_ACCESS_KEY', 'xxxxxxxxxxxxxxxxx' );
$registrationIds = array('id'=>'xxxxxxxxxxxxxxxx');
// prep the bundle
$msg = array

    'message'   => 'here is a message. message',
    'title' => 'This is a title. title',

echo $result;

Response:

{message = here is a message. message, title = This is a title. title }

But above response is not proper json format. Kindly please help me that how to send the FCM notification response as a proper JSON format.

Android code is given below:

public class FireMsgService extends FirebaseMessagingService {

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        super.onMessageReceived(remoteMessage);
        Log.e("remoteMessage-", "remoteMessage--->" + remoteMessage.getData());
        // Log.e("getnotification-", "getnotification--->" + remoteMessage.getNotification());
        Intent intent = new Intent(this, EventFragment.class);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 1410, intent,
                PendingIntent.FLAG_ONE_SHOT);
        Uri sound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                //.setSmallIcon(getNotificationIcon())
                .setContentTitle("Event Application")
                .setContentText("Quiz notification")
                .setAutoCancel(true)
                .setSound(sound)
                .setContentIntent(pendingIntent)
                .setSmallIcon(getNotificationIcon());
        NotificationManager notificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    }

    private int getNotificationIcon() {
        boolean useWhiteIcon = (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP);
        return useWhiteIcon ? R.drawable.a_option : R.drawable.a_option;
    }
}

i am getting response using remoteMessage.getData().

and Firebase ID class is

public class FireIDService extends FirebaseInstanceIdService {

    @Override
    public void onTokenRefresh() {
        super.onTokenRefresh();
        String tkn = FirebaseInstanceId.getInstance().getToken();
        Log.e("tkn","tkn---->"+tkn);
    }
}

Firebase send the Push notification message as a Map object. To get the map as JSON formate you can use the JSONObject class.

So, The parsing will be like this->

JSONObject jsonData = new JSONObject(remoteMessage.getData());

You can also make a POJO class and parse using GSON library.
