Имея такой код:
[code]
<?
class nav{
var $links;
var $page;
var $total;
function ends(){

if ($this->page != 1) $pervpage = '<a href= '.$this->links.'1><<</a> <a href= '.$this->links.''. ($this->page - 1) .'><</a> ';

if ($this->page != $this->total) $nextpage = ' <a href= '.$this->links.''. ($this->page + 1) .'>></a> <a href= '.$this->links.'' .$this->total. '>>></a>';

if($this->page - 2 > 0) $page2left = ' <a href= '.$this->links.''. ($this->page - 2) .'>'. ($this->page - 2) .'</a> | ';
if($this->page - 1 > 0) $page1left = '<a href= '.$this->links.''. ($this->page - 1) .'>'. ($this->page - 1) .'</a> | ';
if($this->page + 2 <= $this->total) $page2right = ' | <a href= '.$this->links.''. ($this->page + 2) .'>'. ($this->page + 2) .'</a>';
if($this->page + 1 <= $this->total) $page1right = ' | <a href= '.$this->links.''. ($this->page + 1) .'>'. ($this->page + 1) .'</a>';

$text = '<div class="page"><span class="spage">'.$pervpage.$page2left.$page1left.'<b>'.$this->page.'</b></span> '.$page1right.$page2right.$nextpage.'</div></div>';

return $text;
}

}

#
$nav = new nav;
define('TOPAGE',10);
$page=intval($_GET['page']);

$posts = DB::run() -> query("SELECT * FROM `book`" -> rowCount();

$total = intval(($posts - 1) / TOPAGE) + 1;
if(empty($page) or $page < 0) $page = 1;
if($page > $total) $page = $total;
$start = $page * TOPAGE - TOPAGE;

if($posts == 0){error('Ошибка','Сообщений нету!');}

$themes = DB::run()->query("SELECT * FROM `book` ORDER BY `id` DESC LIMIT $start,".TOPAGE.""-> fetchAll();
foreach($themes AS $u){
echo $u['msg'].'<hr>';
}

$nav->links='?page=';
$nav->page=$page;
$nav->total=$total;
echo $nav->ends();
#
?>
[/code]

как его еще можно упростить/уменьшить?
