使用多维关联数组创建 Windows 目录结构

Question

我有一个表示目录结构的多维关联数组。结构信息是从带有parent_ids 的数据库中提取的，以指示层次结构。

我已经成功地从数据库中获取了行并排序到一个类似这样的数组中：

Array
(
    [1] => Array
        (
            [fold_id] => 1
            [fold_name] => Preliminary
            [seq] => 1
            [parent_id] => 0
            [generation] => 1
            [ext_name] => 1 Preliminary
            [children] => Array
                (
                    [9] => Array
                        (
                            [fold_id] => 9
                            [fold_name] => Programming
                            [seq] => 3
                            [parent_id] => 1
                            [generation] => 2
                            [ext_name] => 1.3 Programming
                            [children] => Array
                                (
                                    [10] => Array
                                        (
                                            [fold_id] => 10

                                            [generation] => 3
                                            [ext_name] => Feasibility Study
                                        )

                                    [20] => Array
                                        (
                                            [fold_id] => 20
                                            [fold_name] => Front-End Documents
                                            [seq] => 
                                            [parent_id] => 14
                                            [generation] => 3
                                            [ext_name] => Front-End Documents
                                        )
                                )
                        )
                )      
        )
)

每个子数组中的ext_name 键是实际的文件夹名称。我需要做的是获取这个数组并使用mkdir() 从中创建一个实际的目录结构。

我已经通过为每个嵌套代硬编码一个 foreach 循环来做到这一点，但我想以某种方式做到这一点，允许结构更改而无需更新我的代码，以适应更多代，例如。

你们中的任何 php 大师有更优雅的解决方案吗？

谢谢！！！ 马特

这就是我想出的。似乎工作！我愿意改进！！！

function make_paths(&$tree, $parentPath = '') {
    $pathed = array();

    foreach ($tree AS &$branch) {

        if ( strlen($parentPath) ) {
            $path = $parentPath.'/'.$branch['ext_name'];
        } else {
            $path = $branch['ext_name'];
        }

        if ( array_key_exists('children', $branch) ) {
            $children = make_paths( $branch['children'], $path );
            $pathed[] = $path;
            $pathed[] = $children;
        } else {
            $pathed[] = $path;
        }

        unset($branch);
    }
    return $pathed;
}

然后我只是使用array_walk_recursive() 来获取路径并制作文件夹。
