A simple function is all you need.

function unorderedList($val)
{
    if (is_array($val)) {
        return '
' . 
                implode('
', 
                    array_map('unorderedList', $val)) . 
            '
';
    } else {
        return $val;
    }
}

Test code:

$menu = array('Projects (Menu Level 1)',
              array('Project 1 (Menu Level 2)',
                    'Project 2 (Menu Level 2)',
                    'Project 3 (Menu Level 2)'),
              'News (Menu Level 1)',
              'Contact (Menu Level 1)');


echo unorderedList($menu);
