Directory Helper Question

but if you have images in your subfolder, you can use a recursive method.

a recursive methods is a method who call itself

PHP Code:

$images_directory = directory_map('./images/catalog/', FALSE, TRUE);
$images = array();

function getImages($images_directory){
    foreach ($images_directory as $image_directory){
        if (is_array($image_directory){
           getImages($image_directory);
        }else{
            $images[] = $image_directory;
        }
    }
}


getImages($images_directory);
var_dump($images); 


i'm not sure this methods work like that. i writted it from scratch. but this is how to do a recursive method.
