[php]<?Php
// find out how many rows are in the table

$numrows = $r[0];
// number of rows to show per page
$rowsperpage = 6;
// find out total pages
$totalpages = ceil($numrows / $rowsperpage);
// get the current page or set a default
if (isset($_GET[‘news.php’]) && is_numeric($_GET[‘0’])) {
// cast var as int
$currentpage = (int) $_GET[‘0’];
} else {
// default page num
$currentpage = 1;
} // end if
// if current page is greater than total pages…
if ($currentpage > $totalpages) {
// set current page to last page
$currentpage = $totalpages;
} // end if
// if current page is less than first page…
if ($currentpage < 1) {
// set current page to first page
$currentpage = 1;
} // end if
// the offset of the list, based on current page
$offset = ($currentpage - 1) * $rowsperpage;
