Not entirely sure I follow. A better snippet might have been...

Code:

foreach ($tree as $node) {
   $classes = array();
   if (($current['lft'] >= $node['lft'] && $current['rgt'] <= $node['rgt']) {
      $classes[] = 'active';
   }
   $str .= '<li' . (count($classes) ? ' class="' . implode(' ', $classes) . '"' : '') . '><a href="' . ($node['url']) . '">' . $node['menu_title'] . '</a>';

   if ($CI->page_tree->count_children($node['lft'], $node['rgt'])) {
      $str .= get_menu($CI->page_tree->get_children_where($node['lft'], $node['rgt'], array('hidden' => 0, 'date(publish_date) <=' => date("Y-m-d"), 'show_in_menu' => 1)), $current, $level+1, $max_level);
   }

   $str .= '</li>';
   $i++;
}
