37）PHP,获取数据库数据并在html中显示（晋级4）

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 $result;
         /*
          * 构造函数
          * 主机名，使用者，使用者密码，数据库的名字，查询语句
          */
         public function __construct($config) {
         $this->host=$config['host'];
         $this->User=$config['user'];
         $this->Pwd=$config['pwd'];
         $this->Dbname=$config['dbname'];
         $this->my_sql=$config['sql'];
       $this->link=  $this->connect();
       $this->result=  $this->Query($this->my_sql);
         }

         //成员方法   是用来执行sql语句的方法
         /*
          * 数据库查询函数
          * $sql   string   是你的查询语句
          */
         public function Query($sql)
             //两个参数：sql语句，判断返回1查询或是增删改的返回
         {
             $db = $this->connect();
             $r = $db->query($sql);
             if (isset($r)) {
                 return $r->fetch_all();//查询语句，返回数组.执行sql的返回方式是all，也可以换成row
             } else {
                 return "数据库查询失败！";
             }

         }
         /*
          * 数据库连接函数
          */
         public function connect(){
             $Link= mysqli_connect($this->host,$this->User,$this->Pwd,$this->Dbname);
             return $Link;
         }

     }
     $sql='select * from zixun;';
     $config=include './BBB.php';
    $shujuku=new db($config);

   include './login.html';
 //var_dump($shujuku->result);

 ?>

我的BBB.php文件展示：

 <?php
     return $config=array(
         'host'=>"localhost",
         'user'=>"root",
         'pwd'=>"root",
         'dbname'=>"thkphp5",
         'sql'=>$sql);

我的html代码展示：

 <!-- 模板文件，利用HTML代码展示数据 -->
 <!DOCTYPE html>
 <html lang="en">
 <head>
     <meta charset="UTF-8">
     <title>比赛列表</title>

         <th>ZX_id</th><th>ZX_name</th><th>ZX_fenlei</th><th>ZX_zuozhe</th><th>更新时间</th><th>浏览次数</th><th>发布状态</th>
     </tr>
     <?php foreach($shujuku->result as $row) : ?>
     <tr>
         <td><?php echo $row[];?></td>
         <td><?php echo $row[];?></td>
         <td><?php echo $row[];?></td>
         <td><?php echo $row[];?></td>
         <td><?php echo $row[];?></td>
         <td><?php echo $row[];?></td>
         <td><?php echo $row[];?></td>
     </tr>
     <?php endForeach;?>
 </table>
 </body>
 </html>

我的结果展示：

数据库代码展示：
