如何按值对php数组进行排序并将数组添加到另一个数组

Question

好的，所以我正在编写一个应用程序，让我可以从注册用户的数据库中查看 Steam 数据。

我遇到了一个问题。首先，多用户的 Steam API 没有标准化。 （例如每次刷新this，用户的位置都会发生变化（这是什么API？！）

由于steam没有标准化API，我得自己做，所以在做了一个json_decode($url, true)之后。它不是一个关联数组。

我想按steam ID（数字）对assoc数组进行排序，并将它们与我自己的用户数据库（也包含steam ID，但可以在数据库中排序）进行匹配，那么我该怎么做那个？

例如

数组 1：

array(3) {
  [0]=>
  array(2) {
    ["steam_id32"]=>
    string(17) "76561198025035234"
    ["name"]=>
    string(7) "Mitsuki"
  }
  [1]=>
  array(2) {
    ["steam_id32"]=>
    string(17) "76561197968270056"
    ["name"]=>
    string(3) "nrn"
  }
  [2]=>
  array(2) {
    ["steam_id32"]=>
    string(17) "76561197982490298"
    ["name"]=>
    string(4) "Ximp"
  }
}

数组 2：

array(1) {
  ["response"]=>
  array(1) {
    ["players"]=>
    array(3) {
      [0]=>
      array(16) {
        ["steamid"]=>
        string(17) "76561197982490298"
        ["communityvisibilitystate"]=>
        int(3)
        ["profilestate"]=>
        int(1)
        ["personaname"]=>
        string(53) "……‮‮‮‮‮‮‮‮‮‮Ximp ……FUS RO DAH"
        ["lastlogoff"]=>
        int(1328569605)
        ["profileurl"]=>
        string(34) "http://steamcommunity.com/id/ximp/"
        ["avatar"]=>

对于排序数组，您可以找到所需的所有函数的列表here

更新：

首先您必须从2d 或3d 创建一个1d 数组，您可以使用此代码创建一个易于访问且可排序的数组（这是一个示例）：

<?php
$inArr;//This is the 2D array
$outArr = array();
for($i=0;$i<count($inArr);$i++){
   $outArr[$i] = $inArr[$i][0];
?>

然后您可以使用ksort() 或krsort() 函数对其进行排序。并将数组添加到另一个数组：

<?php
  $stack = array("value1", "value2");
  array_push($stack, "value3", "value4");
  print_r($stack);
?>
