PHP 的一种分页函数

控制器代码

        //获取管理员列表并分页
        $page = (int)($_GET['page'])? (int)($_GET['page']):'1';
        $limit = 1;
        $total = $this->User->getAdminTotal();

        if($total>0)
        {
            $url = "/admin.php?c=index&a=index";
            $this->_data['adminList'] = $this->User->getUserList($page,$limit);
            $this->_data['pagebar'] = $this->pagebarht ( $url, array(), $limit, $page, $total );
        }
