ios-sending notification with firebase
<p>I'm trying to create app with notification. Notification must be sended from php file to firebase and then to device. At first i have tried to send with firebase console and it works perfect. But when i try to send notificaion using php then i have problems. It says successfully sended but i didn't get any notifications. there is my php for sending notification:</p>

<pre><code>&lt;?php 
function send_notification ($tokens, $message)
{

    $url = 'https://fcm.googleapis.com/fcm/send';
    $fields = array(
         'to' =&gt; $tokens,
         'data' =&gt; $message
        );
    $headers = array(
        'Authorization:key = my api 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($ch, CURLOPT_POSTFIELDS, json_encode($fields));
   $result = curl_exec($ch);           
   if ($result === FALSE) {
       die('Curl failed: ' . curl_error($ch));
   }
   curl_close($ch);
   return $result;
}

$data = array("alert" =&gt; "How it is going today");
$token = "fJVM7YrWGQg......";


$message = array("message" =&gt; " FCM PUSH NOTIFICATION TEST MESSAGE");
$message_status = send_notification($token, $message);
echo $message_status;
</code></pre>
