php - RecursiveIteratorIterator - 格式化数组

Question

我目前有一个网站可以显示所有目录和子目录(在 MAC 操作系统上)所以我这里有代码

$Directory = new RecursiveDirectoryIterator('/');
$Iterator = new RecursiveIteratorIterator($Directory);

foreach($Iterator as $name => $object){
   echo "$name<br/>";
}

所以它会回显出目录的所有真实路径(目前在windows环境下工作)

C:\xampp\apache\bin
C:\xampp\apache\bin\.
C:\xampp\apache\bin\..
C:\xampp\apache\bin\ab.exe
C:\xampp\apache\bin\abs.exe
C:\myfolder\mysubfolder
C:\myfolder\mysubfolder\.
C:\myfolder\mysubfolder\..
C:\myfolder\mysubfolder\anotherfile.php
C:\myfolder\mysubfolder\another_folder
C:\myfolder\mysubfolder\another_folder\.
C:\myfolder\mysubfolder\another_folder\..
C:\myfolder\mysubfolder\another_folder\file.txt

我想做的是，显示在列表中所以像这样:

C:\
    xampp\
       apache\
           bin\
               ab.exe
               abs.exe
    myfolder\
       mysubfolder\
           anotherfile.php\
           another_folder\
              file.txt

是否可以像我上面放的那样格式化数组中的数据，而不是完整路径？我不确定如何使用“分解”并将它们分组到新数组中...？

你好，我试过这些代码:

foreach($objects as $name => $object){
$newname=explode('\\', $name);
 print_r($newname);
}

它给了我:

array = { [0] => C:\
[1]=>xampp
[2]=>apache
[3]=>bin}

array = { [0] => C:\ 
[1]=>xampp
[2]=>apache
[3]=>bin 
[4]-> . }

 array = { [0] => C:\ 
[1]=>xampp
[2]=>apache
[3]=>bin 
[4]=>.
[5]=>. . }

    array = { [0] => C:\ 
[1]=>xampp
[2]=>apache
[3]=>bin 
[4]=>ab.exe }

 array = { [0] => C:\ 
[1]=>xampp
[2]=>apache
[3]=>bin 
[4]=>abs.exe }

现在，我不确定如何循环播放它们以便它们在组中回显例如

xampp
  apache
     bin
        ab.exe
        abs.exe

谢谢

DirectoryIterator (+ 递归函数)可以为您做到这一点。

$resutl = RecursiveDirectoryIterator(new DirectoryIterator('/path/to/dir'));

function RecursiveDirectoryIterator(DirectoryIterator $path)
{
    $data = array();
    foreach ($path as $node){
        if ($node->isDir() && !$node->isDot()){
            $data[$node->getFilename()] = RecursiveDirectoryIterator(new DirectoryIterator($node->getPathname()));
        }
        elseif ($node->isFile()){
            $data[] = $node->getFilename();
        }
    }
    return $data;
}
