今天测试用小程序调用API接口，发现有些数据打印都是对象，怎么全部打印详细点来

小程序代码：

httpsearch: function (name, offset, type, cb) {    wx.request({      url: 'https://www.tinywan.com/api/wechat/songsSearch',      data: {        name: name,        offset: offset,        limit: 20,        type: type      },      method: 'GET',      success: function (res) {
     var arr = res.data.playlist.item;        for (var x in arr){          console.log(x);          console.log(arr[x]);        }      }    })  }

服务端代码：

public function songsSearch()    {        $name = input('param.name');        $offset = input('param.offset');        $limit = input('param.limit');        $type = input('param.type');        $curlReq = curl_request('http://stream.aliyun.com/api/search/get/',[            's'=>$name,            'limit'=>$limit,            'type'=>$type,            'offset'=>$offset,        ]);        $arrRes = json_decode($curlReq,true);        $newArr = [];        foreach ($arrRes['result']['songs'] as $key=>$val){            $newArr[] = [                'id'=>$val['id'],                'name'=>$val['name'],                'creatorId'=>$val['artists'][0]['id'],                'creator'=>$val['artists'][0]['name'],                'img1v1Url'=>$val['artists'][0]['img1v1Url'],            ];        }        $res = [            'code' => 200,            'msg' => 'success',            'playlist' =>[                'item'=> $newArr,                'songCount'=> $arrRes['result']['songCount'],            ]        ];        return json($res);    }

打印结果
