Question

我正在使用API从betsapi中提取足球数据。由于我不是JSON的专家，我在这里分享我的疑问。我的json输出看起来像这样：

{  
"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，也不会产生任何错误。

如果有人能指出错误，我会非常感激。

这个怎么样：

DispatchQueue.main.async {
    self.performSegue(withIdentifier: "bookingSuccess", sender: nil)
}

然后，循环结果

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

还要参加锦标赛：

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

要在每场锦标赛中循环参赛，请尝试以下方式：

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

我们如何在php中正确打印JSON输出数据？
