任何未注册的用户都可以登录（PHP）

Question

我正在为我的网站登录，当我登录时不检查用户是否已经存在于数据库中。即使您尚未注册，它也允许任何人登录。

这是登录的代码。

<?php


     //database details
      $servername = "localhost";
      $username = "myname";
      $password = "******";
      $dbname = "mydb";


      // Create connection
      $conn = mysqli_connect($servername, $username, $password, $dbname);
      session_start();        

      if(isset($_POST['email']))

    {
        $email = $_POST ['email'];
        $password =$_POST ['password'];


        $query = "SELECT * FROM Users WHERE Email='$email' AND Password='$password'";


        $result = mysqli_query($conn, $query);





         if($result==1)
        {

           header('Location: profile.php');
           exit();
        }

        else
        {

       header('Location: failedlogin.html');
       exit();
        }


    }
