下面是10个数组

pid为0的是顶级导航 有3个 id为0,1,2 也就是讨论 下载 官方区
pid不为0的是子导航 有7个 id为3,4,5,6,7,8,9 也就是求助交流 技术分享 电子书 软件 反馈 综合讨论 程序发布
子导航的pid就是顶级导航的id 也就是讨论下面是求助交流 技术分享 综合讨论

现在需要写一个函数 参数就是那十堆数组 要求返回一个数组$return

$return['top']就是那些顶级导航数组 3组数组
array(3){..顶级导航`讨论 下载 官方区数组..}

$return['child']就是那些子导航数组 注意的是也是3组数组 也就是和顶级数组对应
array(3){
[0] => array(3){..求助交流 技术分享 综合讨论数组.}
[1] => array(2){..电子书 软件数组..}
[2] => array(2){..反馈 程序发布数组..}
}
数组1属于讨论数组的子导航数组
数组2是下载数组的子导航数组
数组3就是官方区数组的子导航数组
