function pager_array($array, $limit = 20, $element = 0) {
global $pager_page_array, $pager_total, $pager_total_items;
$page = isset($_GET['page']) ? $_GET['page'] : ”;

$pager_page_array = explode(‘,’, $page);

$pager_total_items[$element] = count($array);
$pager_total[$element] = ceil($pager_total_items[$element] / $limit);
$pager_page_array[$element] = max(0, min((int)$pager_page_array[$element], ((int)$pager_total[$element]) – 1));
return array_splice($array,$pager_page_array[$element]*$limit,$limit);
}

how to use
// this was filled with all elements, and pager_array simply makes the array only have the elements that are to be displayed on the page.
$files = pager_array($files);
foreach($files as $f)
echo “
\n”;
echo theme(‘pager’); // prints out the indexes for browsing to the next page and everything.
