复制代码 代码如下:
$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'];
?>
id: |
name: |
