*
*/
function multi($num, $perpage, $curpage, $mpurl, $page = 10) {
$multipage = ;
$realpages = 1;
if ($num > $perpage){
$offset = 4;
$realpages = @ceil($num / $perpage);
if ($page > $realpages) {
$form = 1;
$to = $realpages;
}else {
$form = $curpage - $offset;
$to = $form + $page - 1;
if ($form < 1) {
$form = 1;
//$to = $curpage + 1 - $form;
if ($to - $form < $page) {
$to = $page;
}
}
}

$multipage = ($curpage > 1 ? <a href=.$mpurl.page=.($curpage - 1).>up</a> : );
for ($i = $form; $i <= $to; $i++) {
$multipage .= $i == $curpage ? <strong>.$i.</strong> :
<a href=.$mpurl.page=.$i.>.$i.</a> ;
}
$multipage .= $curpage < $realpages ? <a href=.$mpurl.page=.($curpage + 1).>next</a> : ;
$multipage = $multipage ? <div class=pages>.$multipage.</div> : ;
}

return $multipage;
