php - 如何生成 3 级服务器端菜单？

Question

我正在尝试使用 php 和 mysql 动态生成以下菜单

 <ul id="prod_nav" class="clearfix">
 <!-- top -->     <li class="active"><a href="05-Pink-02-Category-List.html"    class="top_link"><span class="down">Clothes</span></a>
 <ul>
              <h1> Men </h1>
              <li><a href="ProductsList.php">Shirt         </a></li>
              <li><a href="ProductsList.php">T-shirt       </a></li>
              <li><a href="ProductsList.php">Polo shirt    </a></li>
              <li><a href="ProductsList.php">Formal shoes  </a></li>
              <li><a href="ProductsList.php">Sport shoes   </a></li>
              <li><a href="ProductsList.php">Suit          </a></li>
              <li><a href="ProductsList.php">Underwear     </a></li>
              <li><a href="ProductsList.php">Socks         </a></li>
              <li><a href="ProductsList.php">Pants         </a></li>
   </ul>
            <ul>
              <h1> Women </h1>
              <li><a href="ProductsList.php">Shirt            </a></li>
              <li><a href="ProductsList.php">T-shirt          </a></li>
              <li><a href="ProductsList.php">Polo shirt       </a></li>
              <li><a href="ProductsList.php">High heel shoes  </a></li>
              <li><a href="ProductsList.php">Sport shoes      </a></li>
              <li><a href="ProductsList.php">Wedding clothes  </a></li>
              <li><a href="ProductsList.php">Underwear        </a></li>
              <li><a href="ProductsList.php">Leather          </a></li>
              <li><a href="ProductsList.php">Socks            </a></li>
              <li><a href="ProductsList.php">Pants            </a></li>
            </ul>
          </li>
        </ul>

但我不确定哪种方式是生成菜单的最佳原理？ 我应该使用 while 循环和 if 或 Case 还是 for 循环？

哪种方式是最好的方式？

谢谢

Answer 1

你应该有一个数组

$a=array('shirt','t-shirt','polo shirt','formal shoes','sport shoes','suit','underwear','socks','pants');

并像这样使用它:

<ul>
<h1>MEN</h1>
<?php foreach($a as $val) :?>
<li><a href="ProductsList.php"><?php echo $val; ?></a></li>
<?php endforeach ;?>
</ul>

<ul>
<h1>womaen</h1>
<?php foreach($a as $val) :?>
<li><a href="ProductsList.php"><?php echo $val; ?></a></li>
<?php endforeach ;?>
</ul>
