简单分页思路

<?php

$sql = 'select * from tablename ';

$res =  mysql_query($sql);

$num =  mysql_fetch_row($res);      //返回总的行数

if(empty($_GET['page']))
{
	$page = 0;
}
else
{
	$page = $_GET['page'];
	if($page < 0)
	{
		$page = 0;
	}
	if($page >= ceil($num/10))           //ceil()  -> 返回 向上舍入为最接近的整数
	{
		$page = ceil($num/10) - 1;
	}
}

mysql_query('select * from tablename order by id limit '.$page.',10');
?>
<a href="page.php?page=0">首页</a>
<a href="page.php?page=<?=$page-1?>">上一页</a>
<a href="page.php?page=<?=$page+1?>">下一页</a>
<a href="page.php?page=<?=ceil($num/10)-1?>">尾页</a>
