在 PHP 中从 JSON 获取单个项目

Question

我正在搜索堆栈溢出，但没有找到我想要做的事情... 所以这里是问题： 如何 RETURN 仅使用蒸汽？

代码：

<?php
// define variables and set to empty values
$steamID = "";
if ($_SERVER["REQUEST_METHOD"] == "POST") {
  $steamID = test_input($_POST["steamID"]);
}
function test_input($data) {
  $data = trim($data);
  $data = stripslashes($data);
  $data = htmlspecialchars($data);
  return $data;
}
$keyApp = '5DE00EE4D07BA728EDAB0B3C2961AA6B';
$api = "";
$json_data = file_get_contents("http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key=$keyApp&steamids=$steamID");
$array = json_decode($json_data, true);
var_dump($array);
?>

var_dump:

array(1) {
  ["response"]=>
  array(1) {
    ["players"]=>
    array(1) {
      [0]=>
      array(19) {

如何从 $array 中提取 steamid？已经试过这个链接 https://www.codewall.co.uk/how-to-read-json-file-using-php-examples/ https://www.php.net/manual/pt_BR/function.json-decode.php

Answer 1

通过访问 steamid 的正确路径，唯一的问题是，显然您可能在玩家数组中有多个项目。所以你可能需要某种循环。

可能是这样的：

$players = $array['response']['players'];

foreach($players as $player) {
  echo $player['steamid'] . '<br>';
}

或者如果你的玩家数组中总是有 1 个玩家，你也可以这样做（快速而肮脏）：

echo $array['response']['players'][0]['steamid'];

Answer 2

$steamID = $array['response']['players'][0]['steamid'];
