PHP如何将数组的内容循环成 “链接”+“下拉选择”的样式

PHP怎么将数组的内容循环成 “链接”+“下拉选择”的样式
自己写的一个循环：

PHP code

<?php $videolist = "优酷{span}youku{span}地址1{sl}地址2{sl}地址3{li}土豆{span}tudou{span}土豆地址{li}新浪{span}sina{span}新浪地址1{sl}新浪地址2{sl}新浪地址3{li}";

$list = explode('{li}',$videolist);
    $palylist = '';
    for($i=0;$i<count($list);$i++){
        $video = explode('{span}',$list[$i]);
        if(empty($video[0])) continue ;
        if(empty($video[1])) continue ;
        $play = $i+1;
        //$url = $video[1];
        $palylist .="<a href=\"&play={$play}\" target=\"_blank\">{$video[0]}  ";
        }
        echo $palylist;

?>

以上循环出来的结果是：

HTML code

<a href="&play=1" target="_blank">优酷</a>  <a href="&play=2" target="_blank">土豆</a>  <a href="&play=3" target="_blank">新浪</a>

请问如何循环成如下样式：

HTML code

    <select name="youku">
      <option>优酷</option>
      <option value="地址1">第一集</option>
      <option value="地址2">第二集</option>
      <option value="地址3">第三集</option>
      </select>
     <a href="%E5%9C%9F%E8%B1%86%E5%9C%B0%E5%9D%80">土豆</a>
     <select name="sina">
      <option>新浪</option>
       <option value="地址1">第一集</option>
      <option value="地址2">第二集</option>
      <option value="地址3">第三集</option>
      </select>

$html='';
