How can cookies be used to store the order of images in a gallery instead of saving it directly to a database in PHP?

To store the order of images in a gallery using cookies instead of directly saving it to a database in PHP, you can set a cookie with the order of the images when the user rearranges them. Then, when the page is loaded, you can read the cookie to display the images in the correct order. 

// Set cookie with the order of images
if(isset($_POST['image_order'])) {
    $order = $_POST['image_order'];
    setcookie('image_order', $order, time() + 3600, '/');
}

// Read cookie to display images in correct order
if(isset($_COOKIE['image_order'])) {
    $order = $_COOKIE['image_order'];
    $images = explode(',', $order);
    foreach($images as $image) {
        echo "<img src='path_to_images/$image.jpg' alt='Image'>";
    }
}
