在這里和大家分享一個(gè)非常好用的 Zend Framework 分頁(yè)類
 
具體效果可見(jiàn)本站的分頁(yè)效果， CSS樣式可根據(jù)個(gè)人設(shè)計(jì)感進(jìn)行更變。
 

這里我會(huì)舉例演示如何使用該類， 如下:
 
IndexController.php， 在 Action 中寫入如下代碼:
復(fù)制代碼 代碼如下:
protected  $_curPage = 1;      //默認(rèn)第一頁(yè)
const PERPAGENUM     = 4;      //每頁(yè)顯示條目數(shù)
 
public function indexAction()
{  
    // $this->_blogModel 已實(shí)例化 blog Model
    // $rows -> 獲得到所展示數(shù)據(jù)的總條目數(shù)
    $rows = $this->_blogModel->getTotalRows();
     
    if($pageNum = $this->getRequest()->getParam('page')) {
        //如果有值傳入，覆蓋初始的第一頁(yè)
        $this->_curPage = $pageNum;
    }
     
    //把數(shù)據(jù)表中的數(shù)據(jù)傳到前端
    $this->view->blogInfo = $this->_blogModel->getBlogInfo(
                                self::PERPAGENUM, ($this->_curPage-1)*self::PERPAGENUM
                            );
    //實(shí)例化分頁(yè)類，并傳到前端
    $this->view->pagebar = $this->displayPageBar($rows);
}
 
private function displayPageBar($totalRows)
{
    $Pager = new Zend_Pagination($totalRows,self::PERPAGENUM);
    return $Pager->getNavigation();
}

models/Blog.php，寫入如下代碼:
復(fù)制代碼 代碼如下:
public function getBlogInfo($perPageNum = NULL, $limit = NULL)
{
    return $this->fetchAll('1 = 1', 'blog_id desc', $perPageNum, $limit)
                ->toArray();
}
 
public function getTotalRows($where = '1=1')
{
    return $this->fetchAll($where)->count();
}

index.phtml, 寫入如下代碼:
復(fù)制代碼 代碼如下:
<div class="page">
    <!--?php echo $this--->pagebar; ?>
</div>

到這里，就可以看見(jiàn)效果了， 如想追求更好的頁(yè)面效果， 請(qǐng)根據(jù)個(gè)人喜好修改分頁(yè)類，這里就不作詳細(xì)示例
復(fù)制代碼 代碼如下:

這里再簡(jiǎn)單回顧下 Mysql 中的 limit offset
 
假設(shè)數(shù)據(jù)庫(kù)表 blog 存在 13 條數(shù)據(jù)。

語(yǔ)句1：select * from blog limit 9, 4
語(yǔ)句2：select * from blog limit 4 offset 9

//語(yǔ)句1和2均返回表 blog 的第 10、11、12、13 行
//語(yǔ)句1中的 9 表示從表的第十行開(kāi)始， 返回 4 行
//語(yǔ)句2中的 4 表示返回 4 行，offset 9 表示從表的第十行開(kāi)始

如下語(yǔ)句顯示分頁(yè)效果:

語(yǔ)句3：select * from blog limit ($this->_curPage - 1)* self::PERPAGENUM, self::PERPAGENUM;
語(yǔ)句4：select * from blog limit self::PERPAGENUM offset ($this->_curPage - 1) * self::PERPAGENUM;
