How can the separation of pagination/navigation code from the rest of the PHP code improve the functionality of a pagination system?

Separating pagination/navigation code from the rest of the PHP code improves the functionality of a pagination system by making the code more modular and easier to maintain. It also allows for better organization of the code, making it easier to make changes or add new features in the future.

// Pagination class to handle pagination/navigation logic
class Pagination {
    public function generatePaginationLinks($totalPages, $currentPage) {
        // Pagination logic here
    }
}

// Implementation example
$pagination = new Pagination();
$paginationLinks = $pagination->generatePaginationLinks($totalPages, $currentPage);
foreach ($paginationLinks as $link) {
    echo $link;
}
