ok, remove the print_r() line, and uncomment the rest of the foreach loop.

Code:

foreach ($res->result_array() as $r) {
    // push found result onto existing tree
    $tree[$r['id']] = $r;
    // create placeholder for children
    $tree[$r['id']]['children'] = array();
    // find any children of currently found child
    $this->generateTree($tree[$r['id']]['children'],$r['id']);
}
