smarty里foreach的索引问题
{%foreach $info as $entry%}{%/foreach%}
请问这里如何在foreach里获得entry的索引?

------解决方案--------------------
{* The header block is output every five rows *} 
{* 每五行输出一次头部区块 *} 

 
{foreach from=$items key=myId item=i name=foo} 
{if $smarty.foreach.foo.index % 5 == 0} 
 
{/if} 
 
{/foreach} 
Title
{$i.label}
 

.iteration包含当前循环次数,与index不同,从1开始,每次循环增长1。 

iteration和index示例 

{* this will output 0|1, 1|2, 2|3, ... etc *} 
{* 该例将输出0|1, 1|2, 2|3, ... 等等 *} 
{foreach from=$myArray item=i name=foo} 
{$smarty.foreach.foo.index}|{$smarty.foreach.foo.iteration}, 
{/foreach}
