如何在php中正确打印JSON输出数据？

我正在使用API从API中提取足球数据。由于我不是JSON方面的专家，我在这里分享我的查询。我的json输出如下所示：

{  
"success":1,
"results":{  
  "season":{  
     "start_time":"1502402400",
     "end_time":"1526335199",
     "has_topgoals":"1",
     "has_leaguetable":"1",
     "has_lineups":"1",
     "name_1":"Premier League 17\/18",
     "name":"Premier League 17\/18"
  },

  "overall":{  
     "tournaments":[  
        {  
           "name":"Premier League",
           "rows":[  
              {  
                 "pos":"1",
                 "sort_pos":"1",
                 "change":"0",
                 "win":"8",
                 "draw":"1",
                 "loss":"0",
                 "goalsfor":"32",
                 "goalsagainst":"4",
                 "points":"25",
                 "pct":null,
                 "team":{  
                    "id":"708",
                    "name":"Man City",
                    "image_id":"17",
                    "cc":"gb"
                 }
              }

              {  
                 "pos":"20",
                 "sort_pos":"20",
                 "change":"0",
                 "win":"1",
                 "draw":"0",
                 "loss":"8",
                 "goalsfor":"2",
                 "goalsagainst":"19",
                 "points":"3",
                 "pct":null,
                 "team":{  
                    "id":"17189",
                    "name":"Crystal Palace",
                    "image_id":"7",
                    "cc":"gb"
                 }
              }
           ]
        }
     ]
  },

我打印结果的代码是

$obj = [''] // code above

$obj = json_decode($data);

foreach($obj as $result){
   echo $result->season->name; // or

   echo $result->overall->tournaments->name; // or
}

虽然我尝试了很多替代方案，但它不会打印任何内容，也不会给出任何错误

如果有人能指出错误，我将不胜感激。

这个怎么样：

$obj = json_decode($data, true);
print_r($obj); //Should give you your json converted to php array

然后，循环遍历结果

foreach ($obj['results'] as $result) {
  echo $result['season']['name'];
}

此外，还可以循环浏览锦标赛：

foreach ($obj['results']['overall']['tournaments'] as $tournament) {
  echo $tournament['name'];
}

要在每个锦标赛中循环各队，请尝试以下方法：

foreach ($obj['results']['overall']['tournaments'] as $tournament) {
  echo 'Tournament: ' . $tournament['name'] . '<br />';
  foreach ($tournament['rows'] as $row) {
    echo 'Team: #' . $row['team']['id'] . ' ' . $row['team']['name'] . ' (' . $row['team']['image_id'] . ')' . '<br />';
  }
}

foreach（$obj['results']['totall']['tournaments']作为$tourbank）{
回显“锦标赛：”.$Tournament['name']。
；
foreach（$锦标赛['rows']作为$row）{
回显“团队：#”。$row['Team']['id'].'。$row['Team']['name'.'。（“$row['Team']['image_id'.]）。”
；
}
}

var\u dump（）

json解码值<如果数据无法解码，code>json\u decode（）将返回null。@ArtOsi json数据输出已经存在。它只是在循环中缺少了一些东西..锦标赛循环正在工作，尽管结果仍然显示为空白。。在锦标赛的子行中循环的任何提示。感谢您的帮助。您想完成什么？在锦标赛“行”下，有一个子行带有“团队”。无法循环获取信息“image\u id”。感谢您花时间回复。我将标记答案
