iOS一次向更多设备发送推送通知

我有数据库的设备令牌和php脚本，它可以发送通知到ios设备，但我需要帮助如何发送相同的消息到我的数据库中的所有设备令牌?这是我的php代码:

<?
$con0 = mysql_connect("server","usr","pass");
mysql_select_db("table", $con0);   
//$fetch = mysql_query("SELECT * FROM token ORDER BY token");
$result = mysql_query("SELECT * FROM toke ORDER BY token");
while($row = mysql_fetch_array($result)){
    $token=$row['token'];
}
mysql_close();

if($_POST['message']){
    $message = stripslashes($_POST['message']);
    $payload = '{
                    "aps" : 
                        { "alert" : "'.$message.'",
                          "badge" : 1,
                          "sound" : "bingbong.aiff"
                        } 
                }';
    $ctx = stream_context_create();
    stream_context_set_option($ctx, 'ssl', 'local_cert', 'ck.pem');
    stream_context_set_option($ctx, 'ssl', 'passphrase', 'iphonista');
    $fp = stream_socket_client('ssl://gateway.sandbox.push.apple.com:2195', $err, $errstr, 60, STREAM_CLIENT_CONNECT, $ctx);
    if(!$fp){
        print "Failed to connect $err $errstrn";
        return;
    } else {
        print "Notifikace byla odeslána! <br><br><br>";
    }


        $msg = chr(0) . pack("n",32) . pack('H*', str_replace(' ', '', $token)) . pack      ("n",strlen($payload)) . $payload;
        fwrite($fp, $msg);  
    fclose($fp);
}
?>

你能帮我吗?由于
