Dynamic Routes Issue

I am using database driven routes with my HMVC.

As shown here

PHP Code:

require_once(BASEPATH .'database/DB.php');

$db =& DB();

$query = $db->get('layout');

$result = $query->result_array();

$files = scandir(APPPATH . 'modules/catalog/controllers');

var_dump($files);

foreach($result as $row) {

    $folder = '';
                    
    $route[$row['route']] = 'catalog' . '/' . $folder . '/' . $row['route'] . '/index';
}

$route['rugby'] = 'catalog/super_rugby/rugby/index';
$route['rugby/(:any)'] = 'catalog/super_rugby/rugby/index/$1';
$route['rugby/(:any)/(:any)'] = 'catalog/super_rugby/rugby/index/$1/$2'; 


The $row['route'] produces a controller name I have set in database

I would like to know is it possible to detect which folder that file controller is in and use a $folder variable like above?

The var dump of scan dir

PHP Code:

array (size=5)
  0 => string '.' (length=1)
  1 => string '..' (length=2)
  2 => string 'common' (length=6)
  3 => string 'module' (length=6)
  4 => string 'super_rugby' (length=11) 


Update
I have tried it with this code have I done it correct to find files

PHP Code:

require_once(BASEPATH .'database/DB.php');

$db =& DB();

$query = $db->get('layout');

$result = $query->result_array();

$dirname = APPPATH . 'modules/catalog/controllers/';
$findme = "*.php";
$dirs = glob($dirname.'*', GLOB_ONLYDIR);
$files = array();

foreach($result as $row) {

    foreach($dirs as $d) {
        $folder =  basename($d);
    }

    $route[$row['route']] = 'catalog' . '/' . $folder . '/' . $row['route'] . '/index';
    $route[$row['route'] . '/(:any)'] = 'catalog' . '/' . $folder . '/' . $row['route'] . '/index/$1';
    $route[$row['route'] . '/(:any)/(:any)'] = 'catalog' . '/' . $folder . '/' . $row['route'] . '/index/$1/$2';
} 


There's only one rule - please don't tell anyone to go and read the manual.  Sometimes the manual just SUCKS!
