Question

我想在我的网站上显示API https://steamgaug.es/api/v2中的一些信息。

这是我目前的代码：

 $steamStatusJson = @file_get_contents("https://steamgaug.es/api/v2");
 $steamStatus = json_decode($steamStatusJson);
 $csgoStatus = $steamStatus->ISteamGameCoordinator->730->online;
 $csgoplayerssearching = $steamStatus->ISteamGameCoordinator->730->stats->players_searching;
 $csgoplayers =  $steamStatus->ISteamGameCoordinator->730->stats->players_online;

我总是收到此错误消息：

FATAL ERROR语法错误，意外＆＃39; 730＆＃39; （T_LNUMBER），期待标识符（T_STRING）或变量

与您将json解码为对象一样，您不能将数字用作properties names

所以，你需要这一行：

$csgoStatus = $steamStatus->ISteamGameCoordinator->730->online;

应如下：

$csgoStatus = $steamStatus->ISteamGameCoordinator->{"730"}->online;
//                                                 ^^^^^^^

也与这些行相同：

$csgoplayerssearching = $steamStatus->ISteamGameCoordinator->{"730"}->stats->players_searching;
$csgoplayers =  $steamStatus->ISteamGameCoordinator->{"730"}->stats->players_online;

或者，简单地将json解码为数组

$steamStatus = json_decode($steamStatusJson, true);

然后你可以访问它：

$csgoStatus = $steamStatus['ISteamGameCoordinator']['730']['online'];
//....

PHP JSON用数字解码
