                                   echo "<a class='nav-link' href='http://gs.haitou.cc/list/type-1'><i class='fa-bookmark-o'></i>";
                                   echo $value['major_name'];
                                   echo "<i class='fa-angle-right'></i></a>";

Answer 1

给你个思路  递归  判断是否还有下级菜单 否则递归  可以无限级分类 必学的!

Answer 2

你的代码我运行了下，不能成功！提供一个思路给你吧：先判断$value是一维数组还是二维数组，若是一维数组，就按照你那样做，如果是二维数组，而继续用forearm循环！
