使用 PHP glob 获取文件夹 - 深度无限 [英] Get folders with PHP glob - unlimited levels deep

问题描述

我有这个工作函数来查找文件夹并创建一个数组.

I have this working function that finds folders and creates an array.

function dua_get_files($path)
{
    foreach (glob($path . "/*", GLOB_ONLYDIR) as $filename)
    {
        $dir_paths[] = $filename;   
    }
    return $dir_paths;
}

此功能只能查找当前位置上的目录.我想找到子文件夹中的目录路径及其子文件夹等等.

This function can only find the directories on the current location. I want to find the directory paths in the child folders and their children and so on.

该数组仍应是目录路径的平面列表.

The array should still be a flat list of directory paths.

输出数组的示例

$dir_path[0] = 'path/folder1';
$dir_path[1] = 'path/folder1/child_folder1';
$dir_path[2] = 'path/folder1/child_folder2';
$dir_path[3] = 'path/folder2';
$dir_path[4] = 'path/folder2/child_folder1';
$dir_path[5] = 'path/folder2/child_folder2';
$dir_path[6] = 'path/folder2/child_folder3';

推荐答案

如果你想递归地处理目录，你应该看看 RecursiveDirectoryIterator.

If you want to recursively work on directories, you should take a look at the RecursiveDirectoryIterator.

$path = realpath('/etc');

$objects = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path), RecursiveIteratorIterator::SELF_FIRST);
foreach($objects as $name => $object){
    echo "$name
";
}
