这是足球，菜单包括代码

      <td width="20%" valign="top"><?php include 'menu.php'; ?></td>
    </tr>
  </table>      
  <p align="center"><?php include 'footer.php'; ?></td>

检查getfooter代码中的下面的内容

function getfooter()
{
    global $footer;
    //other code
}

现在$footer值在开始时设置为NULL，您再也不会设置它，所以不会包括页脚。

我想在页脚的某个地方代码被卡住了。你能暂时删除页脚中的代码，然后放一个回声看看它是否显示吗？如果它工作正常，那么试着删除这些函数一段时间，看看会发生什么。让我知道。

pharagraph缺少关闭标记。

更换<p align="center"><?php include 'footer.php'; ?></td>

至<p align="center"><?php include 'footer.php'; ?></p></td>
