following error
bool(true) bool(true) string(60) "The registration token is not a valid FCM registration token" string(60) "The registration token is not a valid FCM registration token"

Comment the code at the bottom of the file (firebase.utils.php)
that code is just an example

//FCM TOKEN EXAMPLES

//$sampleFcmUserToken = 'XXXXXXXXXXXXXXXX';
//$tokenTitle = 'TOKEN NOTIFICATION_TITLE @ '. date('H:i:s');
//$tokenMessage = 'TOKEN NOTIFICATION_BODY @  '. date('H:i:s');
//var_dump(sendNotificationToSingleRecipient($sampleFcmUserToken, $tokenTitle, $tokenMessage)); // No custom data
//var_dump(sendNotificationToSingleRecipient($sampleFcmUserToken, $tokenTitle, $tokenMessage, false, array('action' => 'no_action'))); // With custom data

I comment as you said, the result is changed to "bool(true) bool(true" but no notification received.

no notification received.

If this json file is the last one you use (I saw it in your previous posts)

pushertesting-418f9-firebase-adminsdk-vi0mo-171539421c.json

you have to rename it to ---> service_account.json

and put it in the server folder, where there are the php files

Yes, I change name as author recommended, and put it in the root with php file.
Please see attached folder.

function sendNotification($title = "", $body = "", $topic=""){
    $authorization_key = "AAAAfwXXXX:XXXXXXXXXXXXXXX";

    $fb_key_array = ['usertoken1', 'usertoken2'];

    $arrayToSend = ['registration_ids' => $fb_key_array,
                    'notification' => ['title' =>$title , 'body' => $body, 'sound' => 'default'],
                    'priority' => 'high',
                    'data' => ['title' =>$title, 'body' => $body, 'topic'=>$topic]  ];
        
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL,"https://fcm.googleapis.com/fcm/send");
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS,json_encode($arrayToSend));  //Post Fields
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json', 'Authorization: key='.$authorization_key));
    $server_output = curl_exec ($ch);

    curl_close ($ch);
}

Hello sir! This is what I use to send Firebase push notifications in PHP using curl.

I have the FB tokens tied to each user. This allows me to use my own data to query who I want to send to. I believe that you can not send 'registration_ids' and only send 'topic' to send to all users subscribed to that topic.

Thank you!!

Great!
Only a little detail: What do I have to change in these php files to send emojis?
I tried different commands like:

$text_including_emojis = utf8_encode($text_including_emojis);

$text_including_emojis = mb_convert_encoding($text_including_emojis,'UTF-8', mb_list_encodings());

But no success! Instead of emojis only mysterious signs are displayed in my receiving B4X app

 

[FrostCodes]

If you use my php sample, then you can use it like this for example:

<?php
require_once 'firebase.utils.php';
return sendNotificationToTopic('general', '💗 Title 🧡', 'Message body 💜');

 

[Andie]

Thanks a lot for your answer.
I have to be a little bit more specific.

I send a notification via a B4X app in this way:

j.Download2("http://mywebspace.com/firebase.utils.php", _
            Array As String("text", notification_text, "topic", "newMessage")

The string variable notification_text contains regular text as well as emojis which I create via:

Sub emoji_UTS (codepoint As Int) As String
    Dim bc As ByteConverter
    Dim b() As Byte = bc.IntsToBytes(Array As Int(codepoint))
    '
    Return BytesToString(b, 0, 4, "UTF32")
End Sub

Within the firebase.utils.php file I have then the content of notification_text which I asign to a variable my_notifaction in this php script. And at that point I have do something with my_notification to display the emoji.

 

[FrostCodes]

I don't think you need to convert UTF. Did you try sending just the emoji directly?

 

[Andie]

Shame on me! You are absolutely right: To do nothing is the solution. Thank you!!!!

As a little excuse I must mention that I had to do this utf-8 transformation in the old php version with the old cloud messaging api.

You are welcome.
