php和html中的简单登录系统

hi i have tried to make a simple login system. (Without mysql). Im not sure what is wrong with my code and was wondering if someone could help me.

<?php
$user=" ";
$password=" ";
if(isset($_POST['submit'])){

if(($_POST['user'] == $user) and ($_POST['password'] == $password)){
    echo "successful login!";
    }
    else
    {
    echo "Bad Login.";
    }
}
?>
<html>
    <input type="text" name = "user" value = "username" />
    <br>
    <input type="password" name = "password" value = "password" />
    <br>
    <input type="submit" name = "submit" value = "login"/ >
</html>

When i click the login button, nothing happens. Thank you

    As you already know, you should use == instead of =. But here a remark (I post as an answer because in a comment I can't indent the code)

    Why don't you use

    if(($_POST['user'] == $user) and ($_POST['password'] == $password)){
      echo 'success';
      }
    else{
      echo 'Bad login';
      }
