What are the benefits of using a standardized "Affenformular" approach for login/logout functionality in PHP scripts?

Using a standardized "Affenformular" approach for login/logout functionality in PHP scripts helps ensure consistency and security across different parts of a website or application. It simplifies the development process by providing a reusable template for handling user authentication, reducing the chances of errors or vulnerabilities. Additionally, it allows for easier maintenance and scalability as the codebase grows.

<?php
session_start();

function login($username, $password) {
    // Validate username and password
    // If valid, set session variables and redirect to homepage
}

function logout() {
    // Unset session variables and destroy session
    // Redirect to login page
}

if(isset($_POST['login'])) {
    login($_POST['username'], $_POST['password']);
}

if(isset($_GET['logout'])) {
    logout();
}
?>
