Send Firebase Notification to multiple registered Android devices

Question

I want to send firebase notification to all registered token in mysql database for android devices, am using the normal php way of creating array of recipient tokens so that i can send the notification, but when i send notification non of the registered devices receive it. I want to know if there is the need of adding some piece of php codes to work with the firebase so that the job get done, If so how and where should i use it based on my codes or what is wrong with my codes and how can i fix it?

// here is the code for sending notification

 <?php
  $message =$_POST['message'];
     $title=$_POST['title'];
 //firebase server  url
  $path_to_fcm='https://fcm.googleapis.com/fcm/send';
  // Here is the server_key
   $server_key="##########################";
   $conn = mysqli_connect("localhost","db_username","password","database_name");
   $sql = "select * from fcm_info";
   $result = mysqli_query($conn,$sql);
  //HERE IS THE TOKEN 
$tokens = array();
if(mysqli_num_rows($result) > 0 ){
    while ($row = mysqli_fetch_assoc($result)) {
        $tokens[] = $row["fcm_token"];
    }
}
///  HERE IS THE KEY SINGLE RECIPIENT IT WORKS FINE WHEN I INTRODUCE TO THE      RECIPIENT FIELD("to" field)
$key="############";
 $headers= array(
     'Authorization:key='.$server_key, 
     'Content-Type:application/json'
           );
              // here use $tokens as the replace $key
$fields= array('to'=>$token,
'notification'=>array('title'=>$title,'body'=>$message,
  'click_action'=>'com.jrcomjk.firebasemysql_TARGET_NOTIFICATION'
));
   $payload= json_encode($fields);
   $curl_session= curl_init();
   curl_setopt($curl_session,CURLOPT_URL,$path_to_fcm);
   curl_setopt($curl_session,CURLOPT_POST,true);
   curl_setopt($curl_session,CURLOPT_HTTPHEADER, $headers);
   curl_setopt($curl_session,CURLOPT_RETURNTRANSFER,true);
   curl_setopt($curl_session,CURLOPT_SSL_VERIFYPEER,false);
   curl_setopt($curl_session,CURLOPT_IPRESOLVE,CURL_IPRESOLVE_V4);
   curl_setopt($curl_session,CURLOPT_POSTFIELDS,$payload);
       $result =curl_exec($curl_session);     
       curl_close($curl_session); 
   mysqli_close($conn);
?>

Single device notification from Firebase console is working? First check single device notification from Firebase console and then go further — Zaki Pathan, Feb 21 '17 at 06:25
Is there an error response? You're aiming to send to *all your users* but in your code, you're using `to` parameter which is used for a single token. See my [answer here](http://stackoverflow.com/a/39547590/4625829) to see what you can use to send to Multiple Devices. — AL., Feb 21 '17 at 06:48

I see that you declare :$tokens = array(); with "s" but you are using $token without "s" here :

   $fields= array('to'=>$token'notification'=>array('title'=>$title,'body'=>$message,'click_action'=>'com.jrcomjk.firebasemysql_TARGET_NOTIFICATION'));
