What are some common methods for creating a password-protected area on a website using PHP?

To create a password-protected area on a website using PHP, you can use a combination of session variables and basic authentication. First, you need to set up a login form where users can enter their username and password. Upon successful login, you can set a session variable to indicate that the user is authenticated. Then, on the protected pages, you can check for this session variable to determine if the user is allowed access. 

<?php
session_start();

// Check if the user is already logged in
if (!isset($_SESSION['authenticated']) || $_SESSION['authenticated'] !== true) {
    header('Location: login.php');
    exit;
}

// Protected content goes here
echo "Welcome to the password-protected area!";
?>
