Sending Firebase Push Notification

Question

I'm new to android programming and I want to send a push notification to my app through a php script. Below is the code that I have used.

<?php

function send_notification($tokens,$message)
{
    $url = 'https://fcm.googleapis.com/fcm/send';

    $feilds = array
        (
            'registration_ids' =>$tokens,
            'data' => $message
        );

        $headers = array
        (
            'Authorization:key=MY_AUTH_KEY',
            'Content-Type: Application/json'
        );

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,0);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($feilds));

        $result = curl_exec($ch);
        if($result == FALSE)
        {
            die('CURL FAILED : '.curl_error($ch));
        }
        curl_close($ch);

        return $result;
}

$conn = mysqli_connect("localhost","root","","my_tavel_database_all");

$sql = "SELECT reg_token FROM customer_main";

$result = mysqli_query($conn,$sql);

$tokens = array();

if(mysqli_num_rows($result)>0)
{
    while($row = mysqli_fetch_assoc($result))
    {
        $tokens[] = $row["reg_token"];
    }
}

mysqli_close($conn);


$message = array("message" => "FCM test Meaagse");

$message_status = send_notification($tokens,$message);

echo $message_status;

?>

I run this script on my localhost and get the fallowing output.

{"multicast_id":7722789472959616021,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1539494402770756%ab8b1f6bf9fd7ecd"}]}

It says one message is success. but I'm not getting the push notification to my device.But when I'm sending notification from the firebase console, my device recieves the notification. can anyone help?

Maybe you need to change your field array like this:

    if($_POST['send_to']=='topic'){
        $fields = array(
            'to' => '/topics/' . $topic,
            'data' => $requestData,
        );

    }else{

        $fields = array(
            'to' => $firebase_token,
            'data' => $requestData,
        );
    }
