我正在尝试使用Steam的Web API回显某个CS：GO播放器的游戏统计数据。
我抓住了这个文件：
$gamestatlink = file_get_contents('http://api.steampowered.com/ISteamUserStats/GetUserStatsForGame/v0002/?appid=730&key=<<MY API KEY>>&steamid=<<PLAYERS STEAM ID>>&format=json');
$statarray = json_decode($gamestatlink, true);
并尝试用
回显该行echo $statarray['playerstats']['stats'][0]['total_kills'][0];
但是，echo返回空。
文件返回

我使用类似的代码来读取播放器摘要文件，其结构略有不同，但代码可以正常工作。
我正试图抓住value的{{1}}。
我做错了什么？
提前致谢。
编辑：
我不觉得How can I access an array/object?的答案在这里对我有帮助，因为返回数组的结构不同，并且使用了不同的api。
