我的php文件和html文件的位置关系：
然后我的主php文件是b.php，我的那个配置文件是BBB.php，我的html文件是login.html
然后我的b.php代码展示：
<?php
class db
{
public $host ;//= "localhost";//定义默认连接方式
public $User;//= "root";//定义默认用户名
public $Pwd;//= "root";//定义默认的密码
public $Dbname ;//= "thkphp5";//定义默认的数据库名
public $my_sql;
public $link;
public $result;

我的BBB.php文件展示：

我的html代码展示：
