PHP菜单问题

作为一个更大的网站重新设计的步骤之一，我把我们网站的大部分内容放入html文件中，作为包含文件使用。我打算通过URL向PHP模板页面传递一个变量，以调用适当的include

我们的网站有许多程序，每个程序都需要一个索引页以及大约5个子页。这些程序页面需要一个菜单系统在不同页面之间导航。我将页面命名为pagex_1、pagex_2、pagex_3等，其中pagex是页面内容的描述

我的问题是，处理这个菜单系统的最佳方式是什么？是否有方法修改用于到达索引页的初始变量，以便在菜单中创建链接以到达其他页

---

谢谢你的帮助

我将菜单结构存储在一个关联的PHP数组中，如下所示：

$menu = array(
  'index'=>array(
     'title'=>'Homepage',
     'include'=>'home.html',
     'subitems'=>array()
  ),
  'products' => array(
     'title'=>'Products',
     'include'=>'products.html',
     'subitems'=>array(
        'product1'=>array(
           ...
        ),
        'product2'=>array(
           ...
        ),
        'product3'=>array(
           ...
        )
     )
  )
);

使该数组也可用于模板脚本，例如通过include/require。然后在变量中使用分隔符来标识菜单项，就像文件系统对文件夹和文件所做的那样，从而标识要包含的结果页面：

“index”将标识索引页 “产品”将标识产品的起始页 “products/product1”将在products页面中标识product 1子页面

。。。等等。

请在回答中添加一些代码之外的其他详细信息。谢谢删除数组的一个小改动：unset$url、$text、$sub for->unset$child；
