我正在显示这样的用户列表：

<ul>

<?php   $directors = get_users(\'role=director\'); 

        foreach ($directors as $director) { 

            $dir_id = $director->ID;

            $dir_order = get_user_meta($dir_id, \'exit_director_order\', TRUE);

            $dir_link = get_bloginfo(\'home\').\'/?author=\'.$dir_id; 

            if ($dir_id == $director_id ) {

                $dir_class= \'current director-\'.$dir_id;

            } else { 

                $dir_class= \'director-\'.$dir_id;
            }
?>

           <li>
                <a href="<?php print $dir_link; ?>" class="<?php print $dir_class; ?>"><?php echo $director->display_name; ?></a><br>
           </li>


<?php } ?>


</ul>

我想按dir\\u顺序（从最小到最大）对用户进行排序。这些值作为整数存储在数据库中。

我该怎么做呢？

EDIT:

这是解决方案。评论包括：

<?php   $results = get_users(\'role=director\'); 

        foreach ($results as $result) {

            // Get data about each user as an object
            $user = get_userdata($result->ID); 


            // Create a flat array with only the fields we need
            $directors[$user->ID] = array(
                \'dir_order\'     =>  $user->exit_director_order,
                \'dir_id\'        =>  $user->ID,
                \'dir_name\'      =>  $user->first_name.\' \'.$user->last_name        
            );
        }

        // Sort
        sort($directors); 

        // The list
        echo \'<ul id="rightcolumndirector">\';
