RecursiveIteratorIterator - formatting the array

Question

I have a site currently to display all directories and subdirectories (on MAC os) So I have the code here

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

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

so it will echo out all of the real path of the directory (currently working on windows environment)

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

What I want to do is, to display in list so something like:

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

Is it possible to format the data in array like the one I put above, not the full path? I am not sure how to use 'explode' and to group them into new array...?

HI again, I tried these code:

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

and it's giving me:

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 }

Now, I'm not sure how to loop them so they will echo in group eg

xampp
  apache
     bin
        ab.exe
        abs.exe

thanks

DirectoryIterator (+ Recursive Function) can do that for you.

$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;
}

Here is non-recursive version, which works by first sorting the iterated result, then by splitting the amount of paths.

<?
$folder = ".";
$Directory = new RecursiveDirectoryIterator($base);
$Iterator = new RecursiveIteratorIterator($Directory);
$SortedIterator = new SortedIterator($Iterator);

foreach($SortedIterator as $name){
    //   echo $name."\n";
   $path = explode(DIRECTORY_SEPARATOR, $name);
   $file = array_pop($path);
   // it's a directory
   if ($file == ".")
   {
      $file = array_pop($path) . DIRECTORY_SEPARATOR;
   }
   if ($file === "..")
   {
     continue;
   }

   $pathcount = count($path);
   echo str_repeat("    ", $pathcount).$file."\n";
}

# Taken from example: http://stackoverflow.com/questions/2930405/sort-directory-listing-using-recursivedirectoryiterator
class SortedIterator extends SplHeap
{
    public function __construct(Iterator $iterator)
    {
        foreach ($iterator as $item) {
            $this->insert($item);
        }
    }
    public function compare($b,$a)
    {
        return strcmp($a->getRealpath(), $b->getRealpath());
    }
}
