What are some best practices for implementing an intro page for first-time visitors on a PHP website?

When implementing an intro page for first-time visitors on a PHP website, it's important to create a welcoming and informative experience that guides users through the website's features and content. To achieve this, you can use cookies or session variables to track whether a user is visiting the website for the first time and display the intro page accordingly. 

<?php
session_start();

if (!isset($_SESSION['visited'])) {
    // Display intro page for first-time visitors
    $_SESSION['visited'] = true;
} else {
    // Redirect to the homepage for returning visitors
    header('Location: homepage.php');
    exit();
}
?>
