一個翻頁類

老東西了，不少站點都有這個方法了（今天突然發現以前沒用，所以就寫了一下）
------------
<?php
class Page{
    private $totalpage;
    private $stride;
    private $currentpage;
    //設置總頁數
    function setTotalpage($objpage=0){
        $this->totalpage=$objpage;
    }
    //設置當前頁
    function setCurrentpage($objpage=1){
        $this->currentpage=$objpage;
    }
    //設置跨度
    function setStride($objStride=1){
        $this->stride=$objStride;
    }
    //獲得總頁數
    function getTotalpage(){
        return $this->totalpage;
    }
    //獲得跨讀
    function getStride($objStride=1){
        return $this->stride;
    }
    //獲取當前頁
    function getCurrentpage($objpage=1){
        return $this->currentpage;
    }
    //打印分頁
    function Pageprint(){
        for($Tmpa=0;$Tmpa<$this->totalpage;$Tmpa++){
            if($Tmpa+$this->stride<$this->currentpage){//加了跨度還小于當前頁的不顯示
                continue;
            }
            if($Tmpa+$this->stride==$this->currentpage){//剛好夠跨度的頁數
                $p=$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){//大于當前頁+跨度的頁面
                break;
            }
            $willprint.="<a href=\"$_SERVER[PHP_SELF]?page=$Tmpa\"><strong>$Tmpa</strong></a> ";

            if($Tmpa==$this->currentpage+$this->stride){//剛好夠跨度的頁數
                $p=$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();
?>
