高分求一个分页函数或类，象google上的那种

不是差不多的吗
$pg=$currenntPage;
$start=$pg-4;
$end=$pg+5;
if($start<0){
  $end-=$start;
  $start=1;
}
for($i=$start;$i<=$end;$i++)

  1.   

    一个浅显易懂的分页类<?php
    class page{
     /*
      实例：
      $sql = "select count(*) from t_article";
      $db->query($sql);
      $db->next_record();
      $recordcount = $db->f(0);//记录总数
      
      $ofun = new page;
      $ofun->pagearg = "pagenum";//设置分页参数名,默认为page
      $ofun->ar = array("&laquo;首页", "&#8249;前页", "后页&#8250;", "末页&raquo;");//可以设置成图片HTML代码
      $trunpage = $ofun->show_page($recordcount, 20);//得到分页信息
      
      $sql = "select * from t_article order by tdate desc ".$ofun->limit;
      $db->query($sql);
      */ var $pagecount;         //总页数
     
     var $limit = "";        //分页时用到的limit参数
     
     var $pagearg = "page";  //分页参数名称
     
     var $ar = array("&laquo;首页", "&#8249;前页", "后页&#8250;", "末页&raquo;");
     /*
      * 功能：分页函数
      * 参数 $recordcount 为记录总数
      * 参数 $pagesize 为每页显示记录数,默认为20
      */
     function show_page($recordcount, $pagesize = 20){
      $this->pagecount = ceil($recordcount/$pagesize);//总页数
      //取得页码，默认为1
      if(isset($_GET[$this->pagearg])){
       if($_GET[$this->pagearg] <= 0) $page = 1;
       else $page = $_GET[$this->pagearg];
      }else {
       $page = 1;
      }
      $str = "";
      $urlar = $_GET;
      unset($urlar[$this->pagearg]);
      if($urlar){
       foreach($urlar as $key=>$val){
        if($str == "") $str = "?$key=$val";
        else $str .= "&$key=$val";
       }
       $str .= "&$this->pagearg=";
      }else{
       $str = "?$this->pagearg=";
      }
      if($page > $this->pagecount) $page = $this->pagecount;
      
      $this->limit = "limit ".($page-1)*$pagesize.",".$pagesize;
      
      $trunpage = "";
      if($page == 1){
       $trunpage .= $this->ar[0]."&nbsp;".$this->ar[1]."&nbsp;";
      }else {
       $trunpage .= '<a href="'.$str.'1">'.$this->ar[0].'</a> <a href="'.$str.($page-1).'">'.$this->ar[1].'/a> ';
      }
      $trunpage .= "&nbsp;共[$recordcount]条记录/共[$this->pagecount]页&nbsp;";
      if($page == $this->pagecount){
       $trunpage .= $this->ar[2]."&nbsp;".$this->ar[3]."&nbsp;";
      }else {
       $trunpage .= ' <a href="'.$str.($page+1).'">'.$this->ar[2].'</a> <a href="'.$str.$this->pagecount.'">'.$this->ar[3].'</a>';
      }
      $select = "<select onchange='location.href=this.options[this.selectedIndex].value'>\n";
      for($i = 1; $i <= $this->pagecount; $i++){
       $select .= "<option value=\"".$str.$i."\">$i</option>\n";
      }
      $select .= "</select>";
      return $trunpage.$select;
     }
     
    }
    ?>
      

  2.   

    这只是个函式
    function  pagedeal($pagesql, $pagesize)
    {
        global $recordcount, $pagecount, $page, $startloc;
     
    $rs          = mysql_query($pagesql);
    $recordcount = mysql_num_rows($rs); //取得记录总数

    //******计算总页数*******/ 
    if ( $recordcount % $pagesize == 0 )
        $pagecount = $recordcount / $pagesize;
    else
       $pagecount  = intval($recordcount / $pagesize) + 1;
       
    if ( empty($page)||$page<1 )//$page是当前页
        $page = 1;

    if ( $page>$pagecount )
       $page = $pagecount;
       
    $startloc = ($page - 1) * $pagesize;//确定当前页的起始记录    //-----------------当前页的前部分数字分页----------------------//
        if ($page<=5);
        $i = 0;    if ( $page>5 && $pagecount - $page < 5 && $pagecount>10 )
            $i = $pagecount - 10;    if ($page>5 && $pagecount - $page >=5)
            $i = $page - 5;    for (; $i < $page; $i++) 
            $numpage[$i] = $i  + 1;
        //--------------当前页的后半部分(包括当前页)数字分页------------//
        $j = $pagecount;    if ($page<=5 && $pagecount>10)
           $j = 10;    if ($page>5 && $pagecount - $page >=5)
           $j = $page + 5;    for (; $i<$j; $i++) 
           $numpage[$i] = $i+1;
        return $numpage;//返回数字分页}
      

  3.   

    随便瞎写，不觉得GOOGLE那个分页有什么好:(
    就一个函数，自己把参数丢进去，出来的就是页码了。<?
    function page_list($page=1,$pageurl,$max_pages,$list_size=9) //$page 当前页数 $pageurl 处理页的GET地址 $max_pages 最大页数 $list_size 左右各显示多少条
    {
        if(strstr($pageurl,"?"))
        $pageurl.="&page=";
        else
        $pageurl.="?page="; ///要是没传？过来，这页就没什么用了，page=，大概都会用这个来传页数吧     
     
        $page=$page<1?1:$page;
        $page=$page>$max_pages?$max_pages:$page; ///页数不正确后面就完蛋了
        
        $start_page=$page-$list_size;
    $start_page=$start_page<1?1:$start_page;
        $end_page=$page+$list_size;
        $end_page=$end_page>$max_pages?$max_pages:$end_page; ///这次显示的第一页码和最后一页码    for($i=$start_page;$i<=$end_page;$i++)
        {   
            if($i!=$page)
            $page_string.="<a href='$pageurl$i'>$i</a>&nbsp;";
            else
            $page_string.="[ <b>$i</b> ]&nbsp;";
        }
            $prepage=$page-1;
        $nextpage=$page+1;
        if($page>1)
        $page_string="<a href='$pageurl$prepage'>上一页</a>&nbsp;".$page_string;
        if($page<$max_pages)
        $page_string.="<a href='$pageurl$nextpage'>下一页</a>&nbsp;";    ///别忘了加上、下页
       
        echo $page_string; ///大功告成，喜欢的话RETURN也可         
    }
