PHP 按键从不同的结构化多维数组中获取值 - PHP get values by key from different structured multidimensional arrays

>我得到具有不同结构的多维数组，如下所示：

阵列 1：

array(1) {
  ["BrowseNode"]=>
  array(3) {
    ["BrowseNodeId"]=>
    string(9) "364935031"
    ["Name"]=>
    string(17) "Taschen & Schalen"
    ["Ancestors"]=>
    array(1) {
      ["BrowseNode"]=>
      array(3) {
        ["BrowseNodeId"]=>
        string(9) "364918031"
        ["Name"]=>
        string(13) "HandyzubehÃ¶r"
        ["Ancestors"]=>
        array(1) {
          ["BrowseNode"]=>
          array(3) {
            ["BrowseNodeId"]=>
            string(10) "1384526031"
            ["Name"]=>

有没有办法将Name键中的所有值获取到字符串？到目前为止，我已经看到了至少 30 种不同的结构，因此不可能以严格的方式循环数组

该数组组织为树。树最好由递归函数处理。这将可以：

function extract_Name($arr, $path, &$result)
{
    foreach ($arr as $k => $v)
    {
        if ($k == "Name")
        {
            $result[$path . "/" . $k] = $v;
        }
        else if (is_array($v))
        {
            extract_Name($v, $path . "/" . $k, $result);
        }
    }
}
$result = array();
extract_Name($your_struc, "", $result);
var_dump($result);

示例输出：

array(5) {
  ["/BrowseNode/Name"]=>
  string(17) "Taschen & Schalen"
  ["/BrowseNode/Ancestors/BrowseNode/Name"]=>
  string(13) "Handyzubehör"
  ["/BrowseNode/Ancestors/BrowseNode/Ancestors/BrowseNode/Name"]=>
  string(17) "Handys & Zubehör"
  ["/BrowseNode/Ancestors/BrowseNode/Ancestors/BrowseNode/Ancestors/BrowseNode/Name"]=>
  string(10) "Kategorien"
  ["/BrowseNode/Ancestors/BrowseNode/Ancestors/BrowseNode/Ancestors/BrowseNode/Ancestors/BrowseNode/Name"]=>
  string(17) "Elektronik & Foto"
}

如果您只想要名称而没有指向它们的路径，您可以简单地替换：

$result[$path . "/" . $k] = $v;

跟：

$result[] = $v;

在这种情况下，输出将是：

array(5) {
  [0]=>
  string(17) "Taschen & Schalen"
  [1]=>
  string(13) "Handyzubehör"
  [2]=>
  string(17) "Handys & Zubehör"
  [3]=>
  string(10) "Kategorien"
  [4]=>
  string(17) "Elektronik & Foto"
}
