PHP Firebase Notification Script

This repository showcases a simple and effective script to send push notifications to Android devices using Firebase Cloud Messaging (FCM). Designed for developers, the code provides a quick setup for integrating FCM notifications with minimal configuration.

Key Features

• Lightweight PHP implementation.
• Customizable notification content, including title, body, and icons.
• Detailed documentation for ease of use.

Instructions

1. Replace YOUR-SERVER-API-ACCESS-KEY with your FCM server key from the Google API Console.
2. Pass the device's registration ID via a GET request to the script.
3. Execute the script to deliver the notification.

Example Request

http://yourdomain.com/PhpFireBaseNotificationSample.php?id=DEVICE_REGISTRATION_ID

PhpFireBaseNotificationSample.php

<?php

#API access key from Google API's Console
    define( 'API_ACCESS_KEY', 'YOUR-SERVER-API-ACCESS-KEY-GOES-HERE' );
    $registrationIds = $_GET['id'];

#prep the bundle
     $msg = array
          (
		'body' 	=> 'Body  Of Notification',
		'title'	=> 'Title Of Notification',
             	'icon'	=> 'myicon',/*Default Icon*/
              	'sound' => 'mySound'/*Default sound*/
          );

	$fields = array
			(
				'to'		=> $registrationIds,
				'notification'	=> $msg
			);
	
	
	$headers = array
			(
				'Authorization: key=' . API_ACCESS_KEY,
				'Content-Type: application/json'
			);

#Send Reponse To FireBase Server	
		$ch = curl_init();
		curl_setopt( $ch,CURLOPT_URL, 'https://fcm.googleapis.com/fcm/send' );
		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( $fields ) );
		$result = curl_exec($ch );
		curl_close( $ch );

#Echo Result Of FireBase Server
echo $result;

If you are talking about Android, then I think we have the same issue. Go to Settings -> Developer Options and look for "Show notification channel warnings". I think this option is only available on Android 8. Enable it and test it again. If you see something like "failed to post notification on channel 'null', then you do have the same issue as what I have.

Android 8 have this new feature for notification which can be assigned to a channel ID.

I Google this for the entire day and tried several recommendation, but unfortunately I am still trying to find the solution to this.

New api uses this format:
https://fcm.googleapis.com/v1/projects/myproject-b5ae1/messages:send
You have to include project name and version of api.

Also there are changes to auth and payload. More info here: https://firebase.google.com/docs/cloud-messaging/migrate-v1

After trying all sorts of complicated plugins that required complicated installations and giving me so much errors and without success, I am amazed that this simple script works. Wow! Thank you.

Hello team,

Any examples for cordova/phonegap? Been looking around for an example on how to setup the index.html to receive notifications but no luck

Hello team,

hi dear. yes, there is a way. make a route with the top script and in your web application then send the request by your Cordova/PhoneGap?

Thank you.

Your welcome

its simple brother. you just need to define your application and then get the token and put it there. it will work well.

I created a fork available here

What's the difference from the original script ?
-You can send message to a specific device by informing a device ID to the parameter 'id'
-or send a broadcast to a specific topic to the parameter 'topic'.
-it is necessary to set a specific topic previously on your Firebase Console and
also the device must subscribe to it.
-You will also receive a error message if you do not pass any value to those two needed parameters.

Create project on firebase console, It returns me Server Accesss key and Legacy key under Project Overview-> project settings -> Cloud Message.

Copy the legacy server key and put it on your script API_ACCESS_KEY;

Will work.

Your Well Come Dear

Thanks Pal

it worked like magic. So for the benefit of those struggling with this error
"{"multicast_id":5298140393388678667,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"InvalidRegistration"}]}"

I faced this for nearly a week only to discover that i was parsing a wrong device token. the reason being i was getting the token on device ready event through an alert() method. since i couldn`t copy it directly i had to screenshot the result then use some image to text app to get the token as string which is where i got it all wrong. To fix this i had to use use the whatsapp api to send the token to my account as plain text.

then it worked.
