<?php

//-------------------------些为PHP网页程序序分页类--------------------------/

//说明部分:外部可访问函数:

//              【GetPerPage】                    整型              返回当前页

//              【GetTotalPage】                    整型              返回总页数

//              【GetStartEndInfo】              数组              返回首尾号

//              【GetStart】                        整型              返回查询语句开始取数

//              【GetPerNextInfo】              数组              返回上下页数字

//              【GetPerNextMoreInfo】          数组              返回上几页下几页数字

//              【GetPerNext】                    数组              返回封装的上下页

//              【GetPerNextMore】              数组              返回封装的上几页下几页

//              【GetPageHeader】              字符串          返回封装分页头信息

//              【GetPageBody】                    字符串          返回封装的分页主体信息

//              【GetPageEnd】                    字符串          返回封装的分页尾部信息

//              【DisplayPageInfo】              字符串          返回封装的完整分页信息

//使用说明:

//      在所使用的文件中Include()本文件,使用New操作符新创建一个本对象。新创建对象时需设置构造函数所需参数

//  参数说明如下构造函数说明处！
