PHP代码片段破坏HTML标记

我正在尝试将php脚本实现到xhtml模板中。但是，模板的标记与脚本处理模板时略有不同

在模板中，我有菜单项和子菜单项。静态导航菜单中的示例代码如下所示：

<li><a href="#">Men TEES</a></li> <-- is a menu item (note the end </li>)

<li><a href="#">WO Tees</a>  <-- menu item with submenu items
    <ul>
        <li><a href="#">Desktop PCs</a></li>
        <li><a href="#">Laptop PCs</a></li>
        <li><a href="#">TVs</a></li>
        <li><a href="#">Printers &amp; Ink</a></li>
        <li><a href="#">Electronics &amp; Accesories</a></li>
        <li><a href="#">Software</a></li>
        <li><a href="#">Sub Navigation</a>
    <ul>

感谢您的回答，如果一个菜单项包含子菜单项，它不会以

关闭，而是直接以

开始。您希望在categories循环中获得子类别，那么

和
可以在正确的位置打开/关闭

e、 g


您能给出一个输入数组的示例吗？谢谢。谢谢你的回答，如果一个菜单项包含子菜单项，它不会以
关闭，而是直接以
@user1171942开始。我已经更新了我的答案，所以如果子列表中确实有项目，它只输出子列表。
