//为了避免重复包含文件而造成错误,加了判断函数是否存在的条件:
if(!function_exists(pageft)){
//定义函数pageft(),三个参数的含义为:
//$totle:信息总数;
//$displaypg:每页显示信息数,这里设置为默认是20;
//$url:分页导航中的链接,除了加入不同的查询信息“page”外的部分都与这个URL相同。
//   默认值本该设为本页URL(即$_SERVER["REQUEST_URI"]),但设置默认值的右边只能为常量,所以该默认值设为空字符串,在函数内部再设置为本页URL。
function pageft($totle,$displaypg=20,$url=''){
//定义几个全局变量:
//$page:当前页码;
//$firstcount:(数据库)查询的起始项;
//$pagenav:页面导航条代码,函数内部并没有将它输出;
//$_SERVER:读取本页URL“$_SERVER["REQUEST_URI"]”所必须。
global $page,$firstcount,$pagenav,$_SERVER;
//为使函数外部可以访问这里的“$displaypg”,将它也设为全局变量。注意一个变量重新定义为全局变量后,原值被覆盖,所以这里给它重新赋值。
$GLOBALS["displaypg"]=$displaypg;
if(!$page) $page=1;
//如果$url使用默认,即空值,则赋值为本页URL:
if(!$url){ $url=$_SERVER["REQUEST_URI"];}
//URL分析:
$parse_url=parse_url($url);
$url_query=$parse_url["query"]; //单独取出URL的查询字串
if($url_query){
//因为URL中可能包含了页码信息,我们要把它去掉,以便加入新的页码信息。
//这里用到了正则表达式,请参考“PHP中的正规表达式”
$url_query=ereg_replace("(^|&)page=$page","",$url_query);
//将处理后的URL的查询字串替换原来的URL的查询字串:
$url=str_replace($parse_url["query"],$url_query,$url);
//在URL后加page查询信息,但待赋值:
if($url_query) $url.="&page"; else $url.="page";
}else {
$url.="?page";
}
//页码计算:
$lastpg=ceil($totle/$displaypg); //最后页,也是总页数
$page=min($lastpg,$page);
$prepg=$page-1; //上一页
$nextpg=($page==$lastpg ? 0 : $page+1); //下一页
$firstcount=($page-1)*$displaypg;
//开始分页导航条代码:
$pagenav="显示第 <B>".($totle?($firstcount+1):0)."</B>-<B>".min($firstcount+$displaypg,$totle)."</B> 条记录,共 $totle 条记录";
//如果只有一页则跳出函数:
if($lastpg<=1) return false;
$pagenav.=" <a href='$url=1'>首页</a> ";
if($prepg) $pagenav.=" <a href='$url=$prepg'>前页</a> "; else $pagenav.=" 前页 ";
if($nextpg) $pagenav.=" <a href='$url=$nextpg'>后页</a> "; else $pagenav.=" 后页 ";
$pagenav.=" <a href='$url=$lastpg'>尾页</a> ";
//下拉跳转列表,循环列出所有页码:
$pagenav.=" 到第 <select name='topage' size='1' onchange='window.location=\"$url=\"+this.value'>\n";
for($i=1;$i<=$lastpg;$i++){
if($i==$page) $pagenav.="<option value='$i' selected>$i</option>\n";
else $pagenav.="<option value='$i'>$i</option>\n";
}
$pagenav.="</select> 页,共 $lastpg 页";
}
}

//-------------------------具体演示举例------------------------------- /* //(前面程序略) include("pageft.php"); //包含“pageft.php”文件 //取得总信息数 $result=mysql_query("select * from mytable"); $total=mysql_num_rows($result); //调用pageft(),每页显示10条信息(使用默认的20时,可以省略此参数),使用本页URL(默认,所以省略掉)。 pageft($total,10); //现在产生的全局变量就派上用场了: $result=mysql_query("select * from mytable limit $firstcount,$displaypg "); while($row=mysql_fetch_array($result)){ //(列表内容略) } //输出分页导航条代码: echo $pagenav; //(后面程序略) */ ?>

分页类系列之三


<?php

    private $total; //查询所有的数据总记录数 
    private $page; //当前第几页 
    private $num; //每页显示记录的条数 
    private $pageNum; //一共多少页 
    private $offset; //从数据库中取记录的开始偏移数 
    function __construct($total, $page=1, $num=5) { 
        $this->total=$total; 
        $this->page=$page; 
        $this->num=$num; 
        $this->pageNum=$this->getPageNum(); 
        $this->offset=$this->getOffset(); 
    } 
    private function getPageNum(){ 
        return ceil($this->total/$this->num); 
    } 
    private function getNextPage() { 
        if($this->page==$this->pageNum) 
        return false; 
        else
        return $this->page+1; 
    } 
    private function getPrevPage() { 
        if($this->page==1) 
        return false; 
        else
        return $this->page-1; 
    } 
    //数据库查询的偏移量 
    private function getOffset() { 
        return ($this->page-1)*$this->num; 
    } 
    //当前页开始的记录数 
    private function getStartNum() { 
        if($this->total==0) 
        return 0; 
        else
        return $this->offset+1; 
    } 
    //当前页结束的记录数 
    private function getEndNum() { 
        return min($this->offset+$this->num,$this->total); 
    } 
    public function getPageInfo(){ 
        $pageInfo=array( 
        "row_total" => $this->total, 
        "row_num" => $this->num, 
        "page_num" => $this->getPageNum(), 
        "current_page" => $this->page, 
        "row_offset" => $this->getOffset(), 
        "next_page" => $this->getNextPage(), 
        "prev_page" => $this->getPrevPage(), 
        "page_start" => $this->getStartNum(), 
        "page_end" => $this->getEndNum() 
        ); 
        return $pageInfo;

3种分页类使用起来效率都不错,也都很简单,这里推荐给大家。
