destoon实现调用自增数字从1开始的方法

<!--{php $tags=tag("moduleid=14&length=46&condition=status=3&pagesize=10&order=hits desc&template=null");}--> 
               
{loop $tags $k $t}  
 <li>{php $k = ++$k;}  
   <a href="{$t[linkurl]}" rel="external nofollow" target="_blank" class="item"> 
     <span class="num">{$t[hits]}</span>  
     <i class="icon icon2">{$k++}</i>    
     <span class="txt f-ib f-thide">{$t[title]}</span> 
   </a>              
 </li>
{/loop}
