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

问题描述

 函数dua_get_files（$ path）
我有这个工作函数可以找到文件夹并创建一个数组。 {
 foreach（glob（$ path。/ *，GLOB_ONLYDIR）as $ filename）
 {
 $ dir_paths [] = $ filename; 
} 
返回$ dir_paths; 
 
 
 
 $ b 
这个函数只能找到当前位置的目录。我想在子文件夹及其子目录中找到目录路径。
 
 
 
数组仍然应该是目录路径的平面列表。 b 
 $ b 
 输出数组应该看起来像一个例子 
 
 
  $ 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'; 
  
 
 
解决方案
如果您想递归处理目录，看看   RecursiveDirectoryIterator   。
  $ path = realpath（'/ etc'）; 
 
 $ objects = new RecursiveIteratorIterator（new RecursiveDirectoryIterator（$ path），RecursiveIteratorIterator :: SELF_FIRST）; 
 foreach（$ objects为$ name => $ object）{
 echo$ name\\\
; 
} 
  
 
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;
}
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.


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

An example of how the output array should look like
$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';

解决方案
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\n";
}
