How can PHP be used to dynamically generate navigation links for different pages in a guestbook, such as "Previous" and "Next" buttons?

To dynamically generate navigation links for different pages in a guestbook, we can use PHP to calculate the current page number and generate "Previous" and "Next" buttons based on that information. By keeping track of the total number of pages and the current page number, we can create links that navigate to the previous and next pages accordingly. 

<?php
// Assuming $currentPage and $totalPages are available in the context
if ($currentPage > 1) {
    echo '<a href="?page=' . ($currentPage - 1) . '">Previous</a>';
}

if ($currentPage < $totalPages) {
    echo '<a href="?page=' . ($currentPage + 1) . '">Next</a>';
}
?>
