PHP实现分页的一个示例

<?php
if(!$whichpage)
{  
$notepage=1;
}
else
{
$notepage=$whichpage;
}
$noterecs=0;
$pagesize=10;
$bbsconn=mysql_connect("localhost","root");
mysql_select_db("rainwindy",$bbsconn);
$bbsresult=mysql_query("select * from bbs order by id desc",$bbsconn);
$rsnum=mysql_num_rows($bbsresult);
$pagecount=ceil($rsnum/$pagesize);
mysql_data_seek($bbsresult,($notepage-1)*10);
?>
<div align=right>

<table border="0" width="730" cellspacing="0" cellpadding="0">
    <tr>
      <td width="41" height="30" bgcolor="#C0C0C0" bordercolor="#0000FF" valign="middle" align="center">编号</td>
      <td width="100" height="30" bordercolor="#0000FF" bgcolor="#C0C0C0" valign="middle" align="center">用户名</td>

      <td width="239" height="30" bordercolor="#0000FF" bgcolor="#C0C0C0" valign="middle" align="center">发表时间</td>
   </tr>
<?php
while(($bbsrow=mysql_fetch_array($bbsresult)) && ($noterecs<=9))
{

?>
