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

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: 
     
    
 
        } 
while($contents = mysql_fetch_array($rs));//do....while 
$per = $page - 1;//上一页 
$next = $page + 1;//下一页 
echo "
共有".$Total."条记录,每页".$perpagenum."条,共".$Totalpage."页 "; 
if($page != 1) 

echo "首页"; 
echo " 上一页"; 

if($page != $Totalpage) 

echo " 下一页"; 
echo " 尾页
"; 


else如果$total为空则输出No message 

echo "
No message
"; 

?>
