How to send Notification to Android from php?

I have decided to post answer for my own question

Now Google introduced FCM

<?php
define('API_ACCESS_KEY','Api key from Fcm add here');
 $fcmUrl = 'https://fcm.googleapis.com/fcm/send';
 $token='235zgagasd634sdgds46436';

    $notification = [
            'title' =>'title',
            'body' => 'body of message.',
            'icon' =>'myIcon', 
            'sound' => 'mySound'
        ];
        $extraNotificationData = ["message" => $notification,"moredata" =>'dd'];

        $fcmNotification = [
            //'registration_ids' => $tokenList, //multple token array
            'to'        => $token, //single token
            'notification' => $notification,
            'data' => $extraNotificationData
        ];

        $headers = [
            'Authorization: key=' . API_ACCESS_KEY,
            'Content-Type: application/json'
        ];

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL,$fcmUrl);
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fcmNotification));
        $result = curl_exec($ch);
        curl_close($ch);

        echo $result;

How to send push notifications to android mobile from php in react-native?

There may be an issue in the structure of the JSON payload you are sending. According to the documentation here: https://firebase.google.com/docs/cloud-messaging/concept-options, it should be structured as follows:

{
  "message":{
    "token":"fL8aUT2un*******************************B2bzLa",
    "notification":{
      "title":"ControlPlus App",
      "body":"New Workorder has been added !! "
    }
  }
}

Cannot send notification from php script to an android app

Actually, there was problem with my $notifyArray variable as I need to pass predefined parameters as defined below in the link:

https://firebase.google.com/docs/cloud-messaging/http-server-ref

$notify=array('to'=>$token,'notification'=>
                             array('title'=>"Title",body'=>"Subtitle"));

How to send push notifications to multiple devices using php script using FCM?

Try to send device ID of multiple devices as an array. In your case,

$registration_ids must be an array of device IDs.

E.g

$registration_ids = array('Device ID 1', 'Device ID 2');

send push notification to android app using php without external cloud like firebase

You couldn't push notification without using cloud service, but you can request for some data from a server and get a response without using cloud service. You can use network libray like volley and retrofit. Here I shows an example of volley

Add the following dependency in your app gradle

dependencies {
    compile 'com.android.volley:volley:1.0.0'
}

Add internet permission in your manifest

<uses-permission android:name="android.permission.INTERNET" />

And add the following in your activity

//specify url
String url = "https:yourIpAddress/file.php";

// make a request
JsonObjectRequest jsonObjReq = new JsonObjectRequest(Method.GET,
        url, null,
        new Response.Listener<JSONObject>() {

            @Override
            public void onResponse(JSONObject response) {
                Log.d(TAG, response.toString());
                //Success
            }
        }, new Response.ErrorListener() {

            @Override
            public void onErrorResponse(VolleyError error) {
                VolleyLog.d(TAG, "Error: " + error.getMessage());
                //Error
            }
        });

//Make a request queue
RequestQueue mRequestQueue = Volley.newRequestQueue(getApplicationContext());

//Add request to requestQueue
mRequestQueue.add(jsonObjReq);
