What are some alternative programming languages or tools that can be used to achieve the same functionality as PHP for logging into websites?

When logging into websites, PHP is commonly used to handle user authentication and session management. However, there are alternative programming languages and tools that can achieve the same functionality, such as Python with Django or Flask, Ruby on Rails, Node.js with Express, or Java with Spring. 

// PHP code snippet for logging into a website
$username = $_POST['username'];
$password = $_POST['password'];

// Perform authentication logic
if ($username === 'admin' && $password === 'password') {
    // Successful login
    session_start();
    $_SESSION['username'] = $username;
    echo 'Login successful!';
} else {
    // Failed login
    echo 'Invalid username or password';
}
