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

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..}

<code>function getFormate($arr){
    $top = $child = array();
    foreach($arr as $val){
        if($val['pid'] == 0){
            $top[] = $val;
        }else{
            $child[ $val['pid'] ][] =    $val; 
        }
    }
    return array('top' => $top, 'child' => array_values($child) );
