Firebase Cloud Messaging using PHP

Question

I'm trying to use PHP to send a notification from my localhost server. But I cannot get it to work. I previously received curl error. I solved it. But now it doesn't yield any errors. I can successfully send notifications from the Firebase console.

I have created FirebaseCloudMessaging.php to send the messages using curl.

 $to,
          'data' => $message,
        );
        return $this->sendPushNotification($fields);
    }

    // Send message to topic subscribers
    public function sendToTopic($to, $message){
        $fields = array(
          'to' => '/topics/'. $to,
          'data' => $message,
        );

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

    // Send push message to multiple devices
    public function sendToMultipleDevices($registrationIds, $message){
        $fields = array(
            'to' => $registrationIds,
            'data' => $message,
        );

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

    // CURL request to Firebase Platform
    private function sendPushNotification($fields){

        require_once __DIR__ . '/config.php';

        // POST variables
        $url = 'https://fcm.googleapis.com/fcm/send';

        $headers = array(
            'Authorization: key=' . FIREBASE_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);

        curl_setopt($ch, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4 );

        // Disable SSL Certificate Support temporary
        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));
        }else{
            json_decode($result);
        }

        // Close connection
        curl_close($ch);

        return $result;


    }

}

And PushNotification.php is a model class for the messages.

title = $title;
    }

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

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

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

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

    public function getPushNotification(){
        $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;
    }
}

Following index.php shows the form and process the form submission.

                                             Include
                                            image

And config.php stores the web API. Is there a way to debug the code? For example to check whether Google accepts my request? Any suggestion is appreciated.

Thank you!
