我试图将我的程序登录转换为OOP，但我得到ArgumentCountError。这是我的家庭作业，你能帮我吗

下面是我的php代码，带有类和登录函数，以及带有小php脚本的HTML登录页面

数据库连接是PDO

当我使用$login=new login启动我的php函数时； $login->login$email，$password，$type；我得到这个错误：

致命错误：Uncaught ArgumentCounter错误：函数Login:：Login的参数太少，在第50行的C:\xampp\htdocs\public\u html\project OOP\include\Login.php中传递了0，而在C:\xampp\htdocs\public\u html\project OOP\include\include\Login.php50:Login->中正好传递了3{main}在第8行的C:\xampp\htdocs\public\u html\project OOP\include\login.php中抛出

我知道这里有很多错误，但我是个初学者

class Login{

   private $email;
   private $password;
   private $type;

   public function login($email,$password,$type){
            if(!empty($_POST['email']) && !empty($_POST['password'])&& !empty($_POST['type'])):
               switch ($_POST['type']) {
                  case 'Buyer':
                     $records = $conn->prepare('SELECT * FROM buyer WHERE email = :email');
                     break;
                  case 'Seller':
                     $records = $conn->prepare('SELECT * FROM seller WHERE email = :email');
                     break;

                  default:
                     break;
               }
               $_SESSION['type'] = $_POST['type'];

               $records->bindParam('email', $_POST['email']);
               $records->execute();
               $results = $records->fetch(PDO::FETCH_ASSOC);

               $message = '';

               if($results && count($results) > 0 && md5($_POST['password'], $results['password'])){
                  $_SESSION['user_id'] = $results['buyer_id'];
                  $_SESSION['name'] = $results['buyer_name'];
                  $_SESSION['email'] = $results['email'];
                  $_SESSION['password'] = $results['password'];
                  $_SESSION['phone'] = $results['phone'];
                  $_SESSION['description'] = $results['description'];
                  $_SESSION['status'] = $results['status'];


                  header("Location: index.php");
               } else {
                  $message = 'Sorry, those credentials do not match';
               }  
            endif;
         }
}
This is only for test
$email = "keno1@gmail.com";
$password = "123456";
$type = "Buyer";

$login = new Login;
$login->login($email,$password,$type);

My HTML code:

<?php

session_start();
if (  isset($_SESSION['user_id']) ){

    header("Location: index.php");
}

require 'database.php';



?>

您的登录函数被解释为构造函数，因为它与类具有相同的名称。请参阅

由于错误报告设置，您不能看到弃用消息

不过，不赞成并不是问题所在，它最终会变成一个致命的错误，因为

$login = new Login;

调用login方法时不带参数，因为PHP将其视为构造函数

不过，您不需要_构造方法，因为该函数实际上不应该是构造函数。您只需更改类或方法的名称，就可以修复错误。

问题在于登录方法与类同名。它被解释为旧式构造函数。我相信问题在于t您正在使用旧版本的PHP。您应该尽快升级到最新版本。还要更改您的类或登录函数的名称，使它们不是相同的名称。
