Question

我需要在文件test.json中解析一些JSON。

{
"players":
    [
      { "SteamId":123, "Username":"Bob", "Kills":5, "Deaths":7, "Rank":1 },
      { "SteamId":456, "Username":"Nick", "Kills":3, "Deaths":2, "Rank":2 },
      { "SteamId":789, "Username":"Moses" "Kills":8, "Deaths":1, "Rank":3 }
    ]
}

如何循环并显示我的数据。到目前为止我的代码var_dump给了我一个NULL

$raw_data = file_get_contents('test.json');

$data = json_decode($raw_data, true);

var_dump($data);

一旦你提到撒母提到的逗号，你的代码就可以了。

要循环并打印一些值，它们看起来像：

foreach($data["players"] as $player){
    print "Steam ID: ".$player['SteamId'];
    print "Username: ".$player['Username'];
    print "Kills: ".$player['Kills'];
    print "Deaths: ".$player['Deaths'];
    print "Rank: ".$player['Rank'];
}

这可以改进为自动使用Key值作为输出，具有以下内容：

foreach($data["players"] as $player){
    foreach($player as $key => $value){
            print $key.": ".$value;
    }
}

取决于您要完成的工作以及如何查看数据，但我希望您使用的是HTML模板。
