In PHP, how do I paginate arrays for beginners?

Pagination is a technique used to divide a large dataset into smaller chunks, so it can be navigated easily. In PHP, you can paginate arrays using a combination of functions like `array_slice` along with pagination controls like "Next" and "Previous". This example illustrates how to paginate an array of items.


            <?php
            // Sample array of items
            $items = range(1, 100); // Array of numbers 1 to 100
            $itemsPerPage = 10; // Define how many items per page
            $currentPage = isset($_GET['page']) ? (int)$_GET['page'] : 1; // Get current page from URL, default to 1

            // Calculate total pages
            $totalItems = count($items);
            $totalPages = ceil($totalItems / $itemsPerPage);

            // Calculate the start and end index for the slice
            $startIndex = ($currentPage - 1) * $itemsPerPage;
            $pagedItems = array_slice($items, $startIndex, $itemsPerPage); // Get the items for the current page

            // Output the paginated items
            echo '<ul>';
            foreach ($pagedItems as $item) {
                echo '<li>' . $item . '</li>';
            }
            echo '</ul>';

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