Question

我正在尝试从musixmatch api中获取数据，已经成功连接成功，但正努力从数字索引的stdclass对象打印值

这是我的json的一个结果：

    "header": {
      "status_code": 200,

            "updated_time": "2017-04-28T14:06:57Z",
            "primary_genres": {
              "music_genre_list": [
                
              ]
            },
            "secondary_genres": {
              "music_genre_list": [
                
              ]
            }
          }
        }
      ]
    }
  }
}

这是我尝试获取track_name

$url = file_get_contents("http://api.musixmatch.com/ws/1.1/track.search?q_artist=justin%20bieber&apikey=MYAPIKEY");
$json = json_decode($url);

foreach($json->message->body->track_list->track as $track) {
echo $track->track_name;
}

上面的代码不会打印任何内容，但是如果我可以打印

$tracks = $json->message->body->track_list['0']->track->track_name;

它将打印轨道名称，但是我当然想打印列表中每个轨道的所有track_name值

任何帮助表示赞赏

您需要如下遍历track_list数组：

$url = file_get_contents("http://api.musixmatch.com/ws/1.1/track.search?q_artist=justin%20bieber&apikey=MYAPIKEY");
$json = json_decode($url);

foreach($json->message->body->track_list as $track_list) {
    echo $track_list->track->track_name;
}

通过JSON数字索引的stdclass对象创建foreach循环
