      while($row=mysql_fetch_array($res))

Edit: Posted before you clarified your question. Here’s a general recursive menu structure.

<?php
function print_menu($menu)
{
  echo "<ul>\n";
  foreach ($menu as $submenu)
  {
    echo "<li>\n";
    echo "<span>{$submenu['name']}</span>\n";
    if (!empty($submenu['children']))
      print_menu($submenu['children']);
    echo "</li>\n";
  }
  echo "</ul>\n";
}

print_menu(
  array(
    array(
      'name' => 'Menu 1',
      'children' => array(
        array(
          'name' => 'Submenu 11',
          'children' => array(
            array('name' => 'Submenu 111'),
            array('name' => 'Submenu 112')
          )
        ),
      )
    ),
    array(
      'name' => 'Menu 2'
    )
  )
);
?>
