關於數組迴圈的一個問題
$config['menu']['member']['coption'] = '搜尋';
$config['menu']['member']['sub'][0]['caption']='百度';
$config['menu']['member']['sub'][0]['url']='http://www.baidu.com';
$config['menu']['member']['sub'][1]['caption']='Google';
$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';


讓它迴圈成這樣

搜尋(主菜單)
百度(子功能表)

[menu] => Array
(
[member] => Array
(
[coption] => 搜尋
[sub] => Array
(
[0] => Array
(
[caption] => 百度
[url] => http://www.baidu.com
)

[1] => Array
(
[caption] => Google
[url] => http://www.google.com
)

[2] => Array
(
[caption] => SOSO
[url] => http://www.soso.com
)

)
