This is how to use the pagination class with database access
be sure you have a connection to your database.

sample.php

<?php
        include_once("pagination.php");
        $page = $_GET['page'];
        $sql = "select id from content order by date desc";
        $result = mysql_query($sql) or die(mysql_error());
        $num_rows = mysql_num_rows($result);
 
        $pageobject = new Pagination(); 
        $pageobject->page_pagination(15, $num_rows,$page, 10);
        $limit = $pageobject->GetSqlLimit();
        
        // display query results here
        
        // display pagination
        echo $pageobject->GetPageLinks();
        
?>
