求助：php网站从windows平台移植到了Linux平台，出现导航的错误

php+mysql的网站，从原来的windows搭建的平台移植到了centos服务器的平台上，其他的都没有问题，就是主页导航看不到了，点了也不管用。
原来生成的主页代码：<li> 
  <!--[if lte IE 6]><a href=""><table><tr><td><![endif]--> 
  <a href="?p=53"  >院情概况</a>
  <ul class="second">
    
<li> 
  <!--[if lte IE 6]><a href=""><table><tr><td><![endif]--> 
  <a href="?p=63" >院情简介</a>
  <ul class="third">
      </ul>
  <!--[if lte IE 6]></td></tr></table></a><![endif]--> 
</li>
 
移植后生成的主页代码：
<li> 
  <!--[if lte IE 6]><a href=""><table><tr><td><![endif]--> 
  <a href="<?=$url?>" <?=$target?> <?=$select?>><?=$data['title'];?></a>
  <ul class="second">
    
<li> 
  <!--[if lte IE 6]><a href=""><table><tr><td><![endif]--> 
  <a href="<?=$url?>" <?=$target?>><?=$data['title'];?></a>
  <ul class="third">
      </ul>
  <!--[if lte IE 6]></td></tr></table></a><![endif]--> 
</li>
