What considerations should be made when deciding whether to use PHP or HTML for implementing a login feature?

When deciding whether to use PHP or HTML for implementing a login feature, consider the security implications and functionality required for the login process. PHP is typically used for server-side processing and can securely handle user input validation, authentication, and session management. HTML, on the other hand, is primarily used for front-end presentation and may not provide the necessary security features for handling sensitive user data. 

<?php
// PHP code for implementing a basic login feature
session_start();

if($_SERVER["REQUEST_METHOD"] == "POST"){
    $username = $_POST['username'];
    $password = $_POST['password'];
    
    // Perform validation and authentication logic here
    
    // Redirect user to dashboard upon successful login
    header("Location: dashboard.php");
    exit();
}
?>

<!DOCTYPE html>
<html>
<head>
    <title>Login Page</title>
</head>
<body>
    <form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
        <input type="text" name="username" placeholder="Username"><br>
        <input type="password" name="password" placeholder="Password"><br>
        <button type="submit">Login</button>
    </form>
</body>
</html>
