特牛的PHP分页

PHP分页器制作，自动生成分面页码，JS调用函数

<?php
class PageView{
    /**页码**/
    public $pageNo = 1;
    /**页大小**/

    /**总记录数**/

    /**偏移量,当前页起始行**/
    public $offSet = 0;
    /**每页数据**/
    public $pageData = array();
    
    /**是否有上一页**/
    public $hasPrePage = true;
    /**是否有下一页**/

 PHP调用

　　　　$pageNo = $_GET['pageNo'];
        if(empty($pageNo)){
            $pageNo = 1;
        }
        //分页数据
        $pageData = News::getNewsPage($pageNo,$pageSize);
       //取得总行数
        $count = News::getNewsCount();
        //创建分页器
        $p = new PageView($count['0']['TOTAL'],$pageSize,$pageNo,$pageData);
　　　　 //生成页码
        $pageViewString = $p->echoPageAsDiv();

效果图如下：
