What are the best practices for handling cases where cookies are disabled in a user's browser when implementing image rotation on a webpage using PHP?

When cookies are disabled in a user's browser, it can affect the functionality of image rotation on a webpage implemented using PHP. To handle this issue, you can use session variables to store the current image index and rotate through the images accordingly. This way, even if cookies are disabled, the image rotation will still work for the user. 

<?php
session_start();

$images = ['image1.jpg', 'image2.jpg', 'image3.jpg']; // Array of image filenames
$currentImageIndex = isset($_SESSION['currentImageIndex']) ? $_SESSION['currentImageIndex'] : 0;

// Display the current image
echo '<img src="' . $images[$currentImageIndex] . '" alt="Image">';

// Rotate to the next image
$currentImageIndex = ($currentImageIndex + 1) % count($images);
$_SESSION['currentImageIndex'] = $currentImageIndex;
?>
