GetUserStatsForGame Json [蒸汽，CS:GO]

Question

如何解码这个json中的"value“？

{
"playerstats": {
    "steamID": "76561198054387800",
    "gameName": "ValveTestApp260",
    "stats": [
        {
            "name": "total_kills",
            "value": 19229
        },

这里是完整的json：http://api.steampowered.com/ISteamUserStats/GetUserStatsForGame/v0002/?appid=730&key=B85FE65EC6076829BEB5080BFADC8B50&steamid=76561198054387800

我已经试过了：

$str = file_get_contents("http://api.steampowered.com/ISteamUserStats/GetUserStatsForGame/v0002/?appid=730&key=".$steamauth['apikey']."&steamids=".$_SESSION['steamid']);
$json = json_decode($str, true);
$totalkills = $json['playerstats']['stats'][0]['total_kills']['value'];
echo $totalkills . PHP_EOL;

请帮帮我:/

我想这会起作用的。

$totalkills = $json['playerstats']['stats'][0]['value'];
echo $totalkills . PHP_EOL;

但是因为stats是一个数组，所以假设totalkill总是在数组的0位置是不安全的。更安全的做法是遍历数组并找到您要查找的值。

foreach ($json['playerstats']['stats'] as $i) {
    if ($i['name'] == "total_kills") {
        echo $i['name'] . " :" . $i['value'];
    }
}
