{pc:get sql="SELECT pictureurls FROM phpcms_picture_data where id = $id" start="0" num="30" return="pictureurls" } {loop $pictureurls $pic_k $r} {php $a=string2array($r[pictureurls])} {loop $a $pic_l $v}  {/loop} {/loop} {/pc}

 还有另外一种，列表栏目组图调用的标签写法：

{pc:content action="lists" catid="$catid" num="10" order="listorder DESC" moreinfo="1" page="$page"}
     
      {loop $data $n $r}
      
       
{$r[title]}
      
      
       {loop string2array($r['pictureurls']) $pic_k $v}{if $pic_k>3}{php break}{/if}
       {/loop}
      
{/loop}
     
{/pc}
