想问一下有没有人做过分页？

如题，我找了哥分页类Riskle_Db_Table_Paginate ，但却不会使用，按照他的提示
And here is how it is used in the controller:

     public function indexAction() {
         $urls = new Riskle_Db_Table_Paginate(new Urls, $this->_getParam('page'));
         $this->view->urlsList = $urls->fetchAll(null, 'datetime DESC');
         $this->view->paginationInfos = $urls->getPaginationInfos();
     }

The view helper takes paginationInfos as an argument:

echo $this->paginate($this->paginationInfos);


，但不知道这个urls是什么东西?

public function indexAction()
    {
                $this->view->title = "Co. Albums";
                $Album = new Album();
               
        // Define limit
        $count = 5;
        // Get total rows
        $totalRows = $Album->fetchAll()->count();           
        // Get total pages
        $totalPages = ceil($totalRows / $count);
            // Define current page
        $page = (int)$this->_getParam("page");
            if ($page < 1 || $page > $totalPages) $page = 1;
            // Define offset
            $offset = ($page - 1) * $count;
               
        $this->view->totalRows   = $totalRows;
        $this->view->totalPages  = $totalPages;
        $this->view->offset      = $offset;
        $this->view->count       = $count;
        $this->view->page        = $page;
            $this->view->albums      = $Album->fetchAll(null, null, $count, $offset)->toArray();
        }

你还是看看上面这段代码吧
