Download PHP paging script

Before using the downloadable paging scripts

The downloadable archives are useful learning references, but older packages can contain historical PHP or markup. When adapting them for a current project, validate request values, use PDO or MySQLi prepared statements, escape HTML output, and use an explicit record order.

<?php
$page = filter_input(INPUT_GET, 'page', FILTER_VALIDATE_INT) ?: 1;
$page = max(1, $page);
$perPage = 10;
$offset = ($page - 1) * $perPage;
?>
