一个翻页类

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
continue;
}
if($Tmpa+$this->stride==$this->currentpage){//刚好够跨度的页数
$p=$this->currentpage-$this->stride-1;
$willprint.="<a href="$_SERVER[PHP_SELF]?page=1"><strong><<</strong></a> <a href="$_SERVER[PHP_SELF]?page=$p"><strong><</strong></a> ";
}
if($Tmpa>$this->currentpage+$this->stride){//大于当前页+跨度的页面
break;
}
$willprint.="<a href="$_SERVER[PHP_SELF]?page=$Tmpa"><strong>$Tmpa</strong></a> ";

if($Tmpa==$this->currentpage+$this->stride){//刚好够跨度的页数
$p=$this->currentpage+$this->stride+1;
$willprint.="<a href="$_SERVER[PHP_SELF]?page=$p"><strong>></strong></a> <a href="$_SERVER[PHP_SELF]?page=$this->totalpage"><strong>>></strong></a>";
}
}
echo $willprint;
}
}
if(isset($_GET[page])){
$page=$_GET[page];
}else{
$page=1;
}
$CC=new Page();
$CC->setTotalpage(1000);
$CC->setCurrentpage($page);
$CC->setStride(5);
$CC->Pageprint();
?>
