关于数组循环的一个问题

Question

$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)
  <a href="wwww.baidu">百度</a>(子菜单)

Answer 1

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
<{$arr.menu.member.sub.coption}>(主菜单)
<{foreach key=key item=item from=$arr.menu.member.sub}>
    <a href="<{$item.url}>"><{$item.caption}></a>(子菜单)
<{/foreach}>

Answer 2

$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';
$config['menu']['member']['sub'][2]['url']='http://www.soso.com';$ar = $config['menu']['member'];
echo $ar['coption'], '<br>';
foreach($ar['sub'] as $v)
  echo "<a href='$v[url]'>$v[caption]</a><br>";

Answer 3

多少充都好。分析后，使用foreach就可以。
