Get folders with PHP glob - unlimited levels deep

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';

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";
