在AngularJS中单独的SessionStorage Vars

Question

目前，我的会话存储空间如下：

我的用户ID和级别显示在同一行。怎么会这样？我在我的Angular loginService中创建了vars，如下所示：

'use strict';
 app.factory('loginService',function($http, $location, sessionService){
return{
    login:function(data,scope){
        var $promise=$http.post('data/user.php',data); //send data to user.php
        $promise.then(function(msg){
            var uid=msg.data;
            var pass=msg.data;
            var level=msg.data;
            if(uid){
                //scope.msgtxt='Correct information';
                sessionService.set('uid',uid);
                //sessionService.set('lvl',level);
                $location.path('/home');
            } 
            if(level){
                sessionService.set('level',level);
                $location.path('/home');
            }
            else  {
                window.alert("Wrong credentials entered");
                scope.msgtxt='incorrect information';
                $location.path('/login');
            }                  
        });
    },

然后在我的登录脚本中，它很简单 - 它检查我的行并根据输入的用户密码和用户名返回level的值。

$user=json_decode(file_get_contents('php://input'));


 if(isset($user)) 
 {

        session_start();

        $useridname = $user->uid;
        $userpass = md5($user->pass);

        $_SESSION['uid']=$user->uid;

        //get level
        $sql = "SELECT lvl FROM dbo.users WHERE userid = '".$useridname."' 
           AND psw = ?";

        $params = array($userpass);
        $stmt = sqlsrv_query($conn,$sql,$params);

      //if query does not work, return false
       if($stmt === false){
        die( print_r( sqlsrv_errors(), true));
       }

           $row = sqlsrv_fetch_array($stmt, SQLSRV_FETCH_ASSOC);
           if($row)
           {
            do{
     //echo "You are being logged in... please wait!";
     //$_SESSION['lvl']=$user->level; 
          print $_SESSION['level'] = $row['lvl'];
          print $_SESSION['uid'];

由于一些奇怪的原因，我不能为我的生活找出如何让他们在自己的线上单独打印。没有打印，它不会在sessionStorage键和值字段中打印。无法解决这个问题，现在已经有几个小时了。

来自Angular社区的任何想法？

已编辑（data.php）：

$_SESSION['uid']=$user->uid;
$_SESSION['level']=$user->level;


//get userid and level from users table according to username and password entered
$sql = "SELECT lvl FROM dbo.users WHERE userid = '".$useridname."' AND psw = ?";

已编辑（services.js）：

 login:function(data,scope){
var $promise=$http.post('data/user.php',data); //send data to user.php
    $promise.then(function(msg,lvl){
        var uid=msg.data;
        var pass=pass.data;
        var level=lvl.data;
           if(uid){
            //scope.msgtxt='Correct information';
            sessionService.set('uid',uid);
            sessionService.set('level',level);
            $location.path('/home');
        }
