php - smarty如何从多维数组中获取元素

Question

我有多维数组...

Array (2)
1 => Array (1)
  Body => Array (4)
    1 => "Color"
    3 => "Metal-Parts"
    4 => "Accessories"
    5 => "Materials"
2 => Array (1)
  Interieur => Array (1)
    2 => "Inner-Bags"

我想得到这样的结果

> Body
    > Color
    > Metal-Parts
    > Accessories
    > Materials
> Interieur 
    >Inner-Bags

但我没有找到结果，我正在使用这段代码..

[{assign var="labelarr" value=$myParam}]

[{foreach from=$labelarr key=key item=item}]

[{foreach from=$item[1] key=key1 item=item1}] 

     <h2>[{$key1}]</h2>   

[{/foreach}]

[{/foreach}]

但是，我得到这样的结果..只打印

身体

所以请帮助我..谢谢....

怎么样

{foreach from=$labelarr key='label_key' item='label'}
   > {$label_key}
   {foreach from=$label item='label_child'}
     > {$label_child}
   {/foreach}
{/foreach}
