firebase notification sample in php . if you like this code follow me and star it . i will follow you and use your codes and share them . Simple PHP FireBase (FCM) script showing how to send an Android push notification. Be sure to replace the SERVER_API_ACCESS_KEY with a proper one from the Google API's Console page. To use the script, just call …

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;

Great code, it worked for me but only a clarification for the guys that will use it: use as API_ACCESS_KEY the server key that is possible to find, from the Firebase console, in project overview -> setting's project -> cloud messaging.

Anyone know how to get the Registration ID for web? I successfully generate this token:

{
  "endpoint":"https://fcm.googleapis.com/fcm/send/1111111:2222222222222222",
  "expirationTime":null,
  "keys":{"p256dh":"aaaaaaaaaaaa","auth":"bbbbbbbbbbbb"}
}

Is it correct that the 11111:2222222 is the Registration ID? I still get MismatchSenderID error just like the people above.

I tried other value but it gives me InvalidRegistration error.

i m getting this message :-
{"multicast_id":7145009148233962961,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1531121690342192%0000000000000000"}]}
but i m not getting notification on server neither any other message please help me.

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

{"multicast_id":8910091881405662450,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"MismatchSenderId"}]}

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.
