Firebase - Send notification using PHP not working

I am currently following the tutorial from this website: http://www.androidhive.info/2012/10/android-push-notifications-using-google-cloud-messaging-gcm-php-and-mysql/

I am able to send notification from the firebase console but failed to do so from PHP.

config_firebase.php

<?php

 // Firebase API Key
define('FIREBASE_API_KEY', 'xxx');

?>

push_firebase.php

<?php 
class Push {

    // push message title
    private $title;
    private $message;
    private $image;
    // push message payload
    private $data;
    // flag indicating whether to show the push
    // notification or not
    // this flag will be useful when perform some opertation
    // in background when push is recevied
    private $is_background;

    function __construct() {

    }

    public function setTitle($title) {
        $this->title = $title;
    }

    public function setMessage($message) {
        $this->message = $message;
    }

    public function setImage($imageUrl) {
        $this->image = $imageUrl;
    }

    public function setPayload($data) {
        $this->data = $data;
    }

    public function setIsBackground($is_background) {
        $this->is_background = $is_background;
    }

    public function getPush() {
        $res = array();
        $res['data']['title'] = $this->title;
        $res['data']['is_background'] = $this->is_background;
        $res['data']['message'] = $this->message;
        $res['data']['image'] = $this->image;
        $res['data']['payload'] = $this->data;
        $res['data']['timestamp'] = date('Y-m-d G:i:s');
        return $res;
    }

}



?>

firebase.php

<?php
class Firebase {

    // sending push message to single user by firebase reg id
    public function send($to, $message) {
        $fields = array(

        return $this->sendPushNotification($fields);
    }

This is the result that I have gotten:

Request:

{"data":{"title":"This is a second test from php","is_background":false,"message":"Second test from php","image":"","payload":{"team":"India","score":"5.6"},"timestamp":"2017-02-28 3:05:55"}}

Response:

"{\"message_id\":5384787464945132888}"

I couldn't find which part went wrong. Does anyone knows what went wrong?

Edited: push_firebase.php

public function getPush() {
        $res = array();
        $res['notification']['title'] = $this->title;
        //$res['data']['is_background'] = $this->is_background;
        //$res['data']['message'] = $this->message;
        //$res['data']['image'] = $this->image;
        //$res['data']['payload'] = $this->data;
        //$res['data']['timestamp'] = date('Y-m-d G:i:s');
        return $res;
    }

firebase.php

// sending push message to single user by firebase reg id
    public function send($to, $message) {
        $fields = array(
            'to' => $to,

        );
        return $this->sendPushNotification($fields);
    }

    public function sendToTopic($to, $message) {
        $fields = array(

        );

        return $this->sendPushNotification($fields);
    }

Request:

{"notification":{"title":"test"}}

Response:

"{\"message_id\":5724949249510866740}"

Android code onMessageReceived:

        if(remoteMessage == null){
            return;

        }

            Log.e(TAG,"Data Payload: " + remoteMessage.getData().toString());
            try{
                JSONObject json = new JSONObject(remoteMessage.getData().toString());
                handleDataMessage(json);
            }catch(Exception e){
                Log.e(TAG,"Exception: " + e.getMessage());
            }
        }
    }

Your array should be something like this for Android then it will work like a charm.

'registration_ids' => array (
                $api_key
        ),
        'notification' => array (
               "title" => "Title",
                "body" => "Body"
        )

The response shows a message_id which means the request is successful.

Did you mean to point out that you weren't able to receive the notification? If so, then this is probably because you were using a data message payload while your Android code is only handling notification message payloads. See Message Types for the description of both.

Push notifications coming from the Firebase Console are classified as notification message payloads. When you add in custom key-value pairs in the Advanced Options, it'll become a combination of both (notification and data in a single payload).

To handle data-only payloads, you'll have to use RemoteMessage.getData(). See Handling Messages in Android for more details.
