Think PHP递归重新排序无限极子分类数组

// 递归重新排序无限极子分类数组
function recursive($array,$pid=0,$level=0){
    $arr = array();
    foreach ($array as $v) {
        if($v['pid'] == $pid){
            $v['level'] = $level;
            $v['html'] = str_repeat('--',$level);
            $arr[] = $v;            
            $arr = array_merge($arr,recursive($array,$v['id'],$level+1));
        }
    }
    return $arr;
}

调用：

public function index(){
    $cateTopList = M('category')->select();
    $cateTopList = recursive($cateTopList);
    $this->assign('cateTopList',$cateTopList);
    $this->display();
}
