What steps should be taken to integrate and customize a pagination function, like a "Next Page" button, for organizing and presenting data in sections on a website?

To integrate and customize a pagination function like a "Next Page" button for organizing and presenting data in sections on a website, you will need to implement a PHP script that handles the pagination logic. This script should calculate the total number of pages based on the total number of items to display and the items per page, and then display the appropriate data for each page. Additionally, you can customize the pagination buttons and styling to match the design of your website. 

<?php
// Define total number of items and items per page
$totalItems = 100;
$itemsPerPage = 10;

// Calculate total number of pages
$totalPages = ceil($totalItems / $itemsPerPage);

// Get current page number
if (isset($_GET['page']) && $_GET['page'] > 0 && $_GET['page'] <= $totalPages) {
    $currentPage = $_GET['page'];
} else {
    $currentPage = 1;
}

// Calculate offset for SQL query
$offset = ($currentPage - 1) * $itemsPerPage;

// Query database for items on current page
// Example: $query = "SELECT * FROM items LIMIT $offset, $itemsPerPage";

// Display items on current page
// Example: foreach ($items as $item) { echo $item['name']; }

// Display pagination buttons
echo "<div>";
if ($currentPage > 1) {
    echo "<a href='?page=".($currentPage - 1)."'>Previous</a>";
}
for ($i = 1; $i <= $totalPages; $i++) {
    echo "<a href='?page=".$i."'".($i == $currentPage ? " class='active'" : "").">$i</a>";
}
if ($currentPage < $totalPages) {
    echo "<a href='?page=".($currentPage + 1)."'>Next</a>";
}
echo "</div>";
?>
