catid="$r" order="updatetime DESC" thumb="1" num="1" return="info"}
{loop
$info $v}

target="_blank"
title="{$v["title']}"{title_style($v)}>{str_cut($v['title'],28)}
{str_cut($v['description'],100)}

{/loop}
{/pc}

{pc:content
action="lists" catid="$r" num="5" order="id DESC" return="info"}

• {loop
  $info $v}
• ·{str_cut($v['title'],40)}
  {/loop}

{/pc}

{if $num%2==0}{/if}
{/if}
{/loop}

{loop subcat(0,0,0,$siteid) $r}{/loop}函数解释：

{loop subcat(0,0,0,$siteid) $r}{/loop}
