In PHP, how do I paginate objects for beginners?

Pagination is a technique used to divide a large set of data into smaller, more manageable parts, which makes it easier to navigate through the information. In PHP, you can paginate objects such as database records, arrays, or any collections of data. Below is a simple example of how to implement pagination in PHP.

<?php // Sample data (e.g., from a database). $items = range(1, 100); // Array with 100 items $itemsPerPage = 10; // Number of items to show per page $totalItems = count($items); // Total number of items $totalPages = ceil($totalItems / $itemsPerPage); // Total number of pages // Get the current page from the query string, default to 1 $currentPage = isset($_GET['page']) ? (int)$_GET['page'] : 1; $currentPage = max(1, min($currentPage, $totalPages)); // Ensure current page is valid // Calculate the offset for the query $offset = ($currentPage - 1) * $itemsPerPage; // Get the items for the current page $currentItems = array_slice($items, $offset, $itemsPerPage); // Display current items foreach ($currentItems as $item) { echo "Item $item <br>"; } // Display pagination links for ($page = 1; $page <= $totalPages; $page++) { echo '<a href="?page=' . $page . '>Page ' . $page . '</a> '; } ?>
