Get data from json and use just one result as value

本文关键字：一个结果数据获取 json | 更新日期: 2023-09-27

>我正在尝试使用 www.football-data.org 来获取足球联赛排名，但我以前从未使用过JSON。

目前我正在使用以下内容：

$uri = 'http://api.football-data.org/v1/soccerseasons/398/leagueTable/';
$reqPrefs['http']['method'] = 'GET';
$reqPrefs['http']['header'] = 'X-Auth-Token:'.$api_key;
$stream_context = stream_context_create($reqPrefs);
$response = file_get_contents($uri, false, $stream_context);
$details = json_decode($response);

尝试获取一个团队的详细信息。目前我正在使用：

echo "<pre>";
print_r($details);
echo "</pre>";

以显示以下内容：

stdClass Object

    [_links] => stdClass Object
        (
            [self] => stdClass Object
                (

                    [away] => stdClass Object
                        (
                            [goals] => 26
                            [goalsAgainst] => 14
                            [wins] => 8
                            [draws] => 4
                            [losses] => 1
                        )
                )

首先，我如何获取这些值并将它们保存为 PHP 中的可用变量？

其次，是否可以将这些数据缩小到一个团队？例如说：

if($details->teamName == 'Manchester United') { $gamesPlayed = $details->gamesPlayed; }

你有一个对象，其中包括一个名为standing的对象数组，它们又具有teamName属性。所以要得到第一个你会做的

if($details->standing[0]->teamName == 'Manchester United')

或者，您可以遍历standing并在有多个条目的情况下获取所有条目

喜欢

foreach($details->standing as $record)
{
   if($record->teamName == 'Manchester United')
      $gamesPlayed=$record->playedGames;
}
