How to Implement Pagination in PHP

Simple PHP Pagination script

This is a mix of HTML and code but it's pretty basic, easy to understand and should be fairly simple to decouple to suit your needs I think.

try {

    // Find out how many items are in the table
    $total = $dbh->query('
        SELECT
            COUNT(*)
        FROM
            table
    ')->fetchColumn();

    // How many items to list per page
    $limit = 20;

    // How many pages will there be
    $pages = ceil($total / $limit);

    // What page are we currently on?
    $page = min($pages, filter_input(INPUT_GET, 'page', FILTER_VALIDATE_INT, array(
        'options' => array(
            'default'   => 1,
            'min_range' => 1,
        ),
    )));

    // Calculate the offset for the query
    $offset = ($page - 1)  * $limit;

    // Some information to display to the user
    $start = $offset + 1;
    $end = min(($offset + $limit), $total);

    // The "back" link
    $prevlink = ($page > 1) ? '<a href="?page=1" title="First page">«</a> <a href="?page=' . ($page - 1) . '" title="Previous page">‹</a>' : '<span class="disabled">«</span> <span class="disabled">‹</span>';

    // The "forward" link
    $nextlink = ($page < $pages) ? '<a href="?page=' . ($page + 1) . '" title="Next page">›</a> <a href="?page=' . $pages . '" title="Last page">»</a>' : '<span class="disabled">›</span> <span class="disabled">»</span>';

    // Display the paging information
    echo '<div id="paging"><p>', $prevlink, ' Page ', $page, ' of ', $pages, ' pages, displaying ', $start, '-', $end, ' of ', $total, ' results ', $nextlink, ' </p></div>';

    // Prepare the paged query
    $stmt = $dbh->prepare('
        SELECT
            *
        FROM
            table
        ORDER BY
            name
        LIMIT
            :limit
        OFFSET
            :offset
    ');

    // Bind the query params
    $stmt->bindParam(':limit', $limit, PDO::PARAM_INT);
    $stmt->bindParam(':offset', $offset, PDO::PARAM_INT);
    $stmt->execute();

    // Do we have any results?
    if ($stmt->rowCount() > 0) {
        // Define how we want to fetch the results
        $stmt->setFetchMode(PDO::FETCH_ASSOC);
        $iterator = new IteratorIterator($stmt);

        // Display the results
        foreach ($iterator as $row) {
            echo '<p>', $row['name'], '</p>';
        }

    } else {
        echo '<p>No results could be displayed.</p>';
    }

} catch (Exception $e) {
    echo '<p>', $e->getMessage(), '</p>';
}

How to create pagination with PDO PHP

Here is a simple approach to pagination:

<?php
$limit = 2;
$query = "SELECT count(*) FROM kategori";

$s = $db->query($query);
$total_results = $s->fetchColumn();
$total_pages = ceil($total_results/$limit);

if (!isset($_GET['page'])) {
    $page = 1;
} else{
    $page = $_GET['page'];
}

$starting_limit = ($page-1)*$limit;
$show  = "SELECT * FROM kategori ORDER BY id DESC LIMIT ?,?";

$r = $db->prepare($show);
$r->execute([$starting_limit, $limit]);

while($res = $r->fetch(PDO::FETCH_ASSOC)):
?>
<h4><?php echo $res['id'];?></h4>
<p><?php echo $res['nama_kat'];?></p>
<hr>
<?php
endwhile;

for ($page=1; $page <= $total_pages ; $page++):?>

<a href='<?php echo "?page=$page"; ?>' class="links"><?php  echo $page; ?>
 </a>

<?php endfor; ?>
