关于数组循环的一个问题
$config['menu']['member']['coption'] = '搜索';
$config['menu']['member']['sub'][0]['caption']='百度';
$config['menu']['member']['sub'][0]['url']='http://www.baidu.com';
$config['menu']['member']['sub'][1]['caption']='谷歌';
$config['menu']['member']['sub'][1]['url']='http://www.google.com';
$config['menu']['member']['sub'][2]['caption']='soso';
$config['menu']['member']['sub'][2]['url']='http://www.soso.com';
让它循环成这样
搜索(主菜单)
  百度(子菜单)
------解决方案--------------------
array
(
[menu] => array
(
[member] => array
(
[coption] => 搜索
[sub] => array
(
[0] => array
(
[caption] => 百度
[url] => http://www.baidu.com
)
[1] => array
(
[caption] => 谷歌
[url] => http://www.google.com
)
[2] => array
(
[caption] => soso
[url] => http://www.soso.com
)
)
)
)
)这样看不就清楚了吗 
smarty
(主菜单)
(子菜单)
