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;

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.
