请问百度这个分页是怎么实现的?


回复讨论(解决方案)

这个问题问的有水平,我竟无言以对。。。

分页应该都差不多 百度也是传了一个参数 &pn=0 
根据pn的值来判断当前是第几页 然后拿个脚印可以拿图片处理?之类的

如果你说的是1 2 3 4 5的显示的话
分页步骤
1.计算总条数
2.获取当前页
3.计算总页数   ceil(总条数/每页数量)
4.计算偏移量 就是limit n,m
5.查询数据  显示数据

注意:第三部你已经算出来总页数了 假设是10页

$str = '';    for($i=1;$i<=10;$i++){        str .= '<a href="#">'.$i.'</a>';    }echo $str;

这样12345的效果就出来了 
然后再来点样式
a{    width:20px;    height:20px;    display:block;    background:#ffffff;    border:1px dashed #ccc;    color:blue;}a:hover{    background:blue;}

马马虎虎 差不多了

假设当前页数是$page
$first_page = max($page - 5, 1);
$end_page = $first_page + 9;
