如何访问PHP中的第三维数组？ [英] How to access a third dimension array in php?

问题描述

我试图访​​问tLastName在此JSON文件：

I am trying to access tLastName in this json file:

{
  "PlayerInfo": {
    "76561198090954934": {
      "uUserID": 1,
      "tFirstName": "[TAG] Flooze",
      "tLastName": "[TAG] Flooze",
      "iInitTimestamp": 1455213482,
      "iLastSeen": 1455667539,
      "tInitIP": "---",
      "tLastIP": "---",
      "iSecondsPlayed": 66990,
      "iConnections": 12,
      "tReason": "Disconnected",
      "bAlive": false
    },
    "76561198001294252": {
      "uUserID": 2,
      "tFirstName": "[HUN] Pepe",
      "tLastName": "[HUN] Pepe",
      "iInitTimestamp": 1455213482,
      "iLastSeen": 1455316439,
      "tInitIP": "---",
      "tLastIP": "---",
      "iSecondsPlayed": 28210,
      "iConnections": 2,
      "tReason": "Disconnected",
      "bAlive": true
    }
  }
}

这是一个清单，许多这些，我想它正好呼应tLastName在PHP中的每个人。

it is a list with many of these and I would like it to echo just "tLastName" for each of them in php.

我已经得到了：

$file = file_get_contents('http://nbd.esy.es/json/jsondb.json');
$json = json_decode($file, true);

所以这个应该把它放到一个数组？

So this should put it into an array?

在先进的感谢！

推荐答案

试试这个：

$file = file_get_contents('http://nbd.esy.es/json/jsondb.json');
$json = json_decode($file, true);

foreach ($json['PlayerInfo'] as $playerInfo) {
    $lastName = $playerInfo['tLastName'];
}
