复制代码 代码如下:
<?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>";
}
?>
