翻页老东西了，不少站点都有这个方法了（今天突然发现以前没用，所以就写了一下）

<?php
class Page{
    private $totalpage;
    private $stride;
    private $currentpage;
    //设置总页数
    function setTotalpage($objpage=0){
        $this->totalpage=$objpage;
    }
    //设置当前页
    function setCurrentpage($objpage=1){
        $this->currentpage=$objpage;
    }
    //设置跨度
    function setStride($objStride=1){
        $this->stride=$objStride;
    }
    //获得总页数
    function getTotalpage(){
        return $this->totalpage;
    }
    //获得跨读
    function getStride($objStride=1){
        return $this->stride;
    }
    //获取当前页
    function getCurrentpage($objpage=1){
        return $this->currentpage;
    }
    //打印分页
    function Pageprint(){
        for($Tmpa=0;$Tmpa<$this->totalpage;$Tmpa++){
            if($Tmpa+$this->stride<$this->currentpage){//加了跨度还小于当前页的不显示
