php和mysql关于分页的问题
用php提取mysql中的信息,把他分页显示
代码:
'.($message_count-$i)."楼".' | ';'."用户名:".$name.' | ';'.''.$email.' | ';
'.$time.' | ';'.$words.' | ';|
'.' '.' | ';
$pre_page=$page-1;
$next_page=$page+1;
echo $page;
$PATH_INFO=pathinfo("http://localhost:250/myphp编程/留言板的分页显示/留言板分页显示.php");
if($page==1)
{
echo "第一页 上一页"." ";
}
else
{
echo "第一页";
echo " ";
echo "上一页";
}
echo " ";
if($page==$page_count)
{
echo "下一页 最后一页  ";
}
else
{
echo "下一页";
echo " ";
echo "最后一页";
echo $page_count;
}
?>
代码的分页显示部分是错误的,书上的path_info()函数用错了,我也不知道怎么用,“http://localhost:250/myphp编程/留言板的分页显示/留言板分页显示.php”是我的文件路径。请问在“下一页”“最后一页”,“第一页”“前一页”的链接是应该怎么写?

$page=$_GET['page'] ? $_GET['page'] : 1; //加上这句。
