请教smarty中如下的数组怎么用section循环输出

Array ( [0] => Array ( [ID] => 1 [date] => 2011-04-11 [time] => 15:03:21 [content] => 大家好啊，我是曹某人，我现在来测试一下，看看正确吧，多谢支持啊！ [comment_total] => 2 ) [comment] => Array ( [0] => Array ( [comment_id] => 1 [comment_date] => 2011-04-05 [comment_time] => 11:21:24 [comment_content] => 恩，恭喜你，测试通过了！ ) ) )

HTML code

{section name=foo loop=$record step=1}
    {$record[foo]}<br />
{/section}

HTML code

<!-- assign('record',$record) -->
{section name=foo loop=$record step=1}
    {$record[foo]}<br />
{/section}
