Question

我知道，这可能非常容易，但可能，工作到很晚才停止我的大脑...... 行。这是我的PHP，它为我制作了两个级别的动态列表。 http://robertr.pastebin.com/K2XvruPr

<?
    $last = NULL;
    $query = "SELECT s.id AS sect_id, s.name AS sect_name, s.alias AS sect_alias, c.name AS cat_name, c.alias AS cat_alias
    FROM data_sections s, data_categories c
    WHERE s.id = c.section_id
    AND s.deleted = 0
    AND c.deleted = 0";
    echo "<ul>\n";
    $result = mysql_query($query);
    while($list = mysql_fetch_array($result)){

        if($last!=$list['sect_name']) {
            echo "<li>".$list['sect_name']."</li>\n";
            $last = $list['sect_name'];
        }
        echo "<ul>";
        echo "<li>".$list['cat_name']."</li>";
        echo "</ul>\n";
    }
    echo "</ul>";
    ?>

视图输出上的所有内容看起来都不错，但源视图不是我想要的。 robertr.pastebin.com/J7bPQeXj（在地址栏中复制粘贴）。

任何人都可以帮助我理解，如何为所有类别制作一次二级UL标签，而不是每种类别。

谢谢！
