本人所发代码全部为本人原创,并且应用在多个项目中. 自己经常用php+mysql分页代码

<?php  
$perpagenum = 10;//定义每页显示几条  
$total = mysql_fetch_array(mysql_query("select count(*) from a"));//查询数据库中一共有多少条数据  
$Total = $total[0];                          //  
$Totalpage = ceil($Total/$perpagenum);//上舍，取整  
if(!isset($_GET['page'])||!intval($_GET['page'])||$_GET['page']>$Totalpage)//page可能的四种状态  
{  
    $page=1;  
}  
else  
{  
    $page=$_GET['page'];//如果不满足以上四种情况，则page的值为$_GET['page']  
}  
$startnum     = ($page-1)*$perpagenum;//开始条数  
$sql = "select * from a order by id limit $startnum,$perpagenum";//查询出所需要的条数  
echo $sql."  
";  
$rs = mysql_query($sql);  
$contents = mysql_fetch_array($rs);  
if($total)如果$total不为空则执行以下语句  
{  
    do  
    {  
    $id = $contents['id'];  
    $name = $contents['name'];  
    ?>  
    <table border="0" align="center">  
    <tr>  
    <td>id:  
    <?php echo $id;?>  
    </td>  
    </tr>  
    <tr>  
    <td>name:  
    <?php echo $name;?>  
    </td>  
    </tr>  
    </table>  
    <?php  
    }  
while($contents = mysql_fetch_array($rs));//do....while  
$per = $page - 1;//上一页  
$next = $page + 1;//下一页  
echo "<center>共有".$Total."条记录,每页".$perpagenum."条,共".$Totalpage."页 ";  
if($page != 1)  
{  
echo "<a href='".$_SERVER['PHP_SELF']."'>首页</a>";  
echo "<a href='".$_SERVER['PHP_SELF'].'?page='.$per."'> 上一页</a>";  
}  
if($page != $Totalpage)  
{  
echo "<a href='".$_SERVER['PHP_SELF'].'?page='.$next."'> 下一页</a>";  
echo "<a href='".$_SERVER['PHP_SELF'].'?page='.$Totalpage."'> 尾页</a></center>";  
}  
}  
else如果$total为空则输出No message  
{  
echo "<center>No message</center>";  
}  
?>
