<?php
$arr_click = array (
array ( 'clicks' => 3, 'clickDate' => '2010-10-11' ),
array ( 'clicks' => 2, 'clickDate' => '2010-10-11' ),
array ( 'clicks' => 3, 'clickDate' => '2010-10-09' ),
array ( 'clicks' => 1, 'clickDate' => '2010-10-08' ),
);
$page = 2;
$indexinpage =2;
$newarr = array_slice ( $arr_click , ( $page -1)* $indexinpage , $indexinpage );
?>

原理如下:
和分页原理一样
数组用 array_slice(array,offset,length) 函数在数组中根据条件取出一段值。
- array:需要处理的数组
- offset:取出元素的开始位置
- length:返回数组的长度
在每页中改变 offset 的值就行了!

<a href= "ad.php?page=<?php echo $page - 1 > 0? $page - 1: 1; ?>" rel= "external nofollow" >上一页</a>
<a href= "ad.php?page=<?php echo $page + 1 < $pnum? $page + 1: $pnum; ?>" rel= "external nofollow" >下一页</a>
