Paging with PHP

I trolled around the interwebz for a good 3 hours the other night looking for this.
I wanted to page through my mysql query’s resultset rather than display what could potentially be thousands of records on a single page. I wanted to limit the results per page to a certain, low number and display “Previous/Next Page” links at the end of that limited count.

Although I have to say that such a task is done very simply in asp.NET, I thoroughly enjoyed the challenge of doing it in PHP.

The first thing we need to do is find where the start of the page will be in the resultset. To do this, we pass a value to use in the mysql query. This value will just contain a number to indicate which page we’re on.

$page = $_GET[‘page’];
if (!isset($page)) {
header(‘Location: /mysite/index.php?page=1’);

$sql = ‘SELECT * FROM articles LIMIT ‘.($page – 1) * 10.’, 10′;
$result = $dbh->prepare($sql);

foreach ($result->fetch() as $row) {
// Build each

here to display results.

$sql = ‘SELECT COUNT(*) FROM articles’
$result = $dbh->execute($sql);
$count = $result->fetch();

if ($page > 1) {
echo ‘Previous‘;
if ($count > $page) {
echo ‘Next‘;

The code might not be 100% accurate as I just wrote this off the top of my head. I hope it gives you an idea how to do this anyway.

Good luck!
