List files and subfolders from database in PHP

Beginner : I cant seem to get my head around the logic of it. Have searched but seems to come up with listing files and folders from an actual directory ie. (opendir).

My problem is :

Im trying to work out (in PHP) how to list files and subfolders from a path stored in a database. (Without any access to the file or dir, so just from the path name)

For example database shows:

main/home/television.jpg
main/home/sofa.jpg
main/home/bedroom/bed.jpg
main/home/bedroom/lamp.jpg

So if i specify main/home - it shows: television.jpg, sofa.jpg and the name of the subfolder : bedroom.

scanFolder('main/home');

function scanFolder($dir) {

    foreach (scandir($dir) as $file) {

        if (!in_array($file, array('.', '..'))) {

            if (is_dir($file)) {

                scanFolder($dir . '/' . $file);
            }
            else {

                echo $dir . '/' . $file . "\n";
            }
        }
    }
}

You would probably want to check on each iteration if the filename is a directory or not. If it is, open it up and read its contents and output them. A recursive function would work best in this situation.
