方法一: php$arr_click = array( array( 'clicks' = 3, 'clickDate' ='2010-10-11' ), array( 'clicks' = 2, 'clickDate' ='2010-10-11' ), array( 'clicks' = 3, 'clickDate' ='2010-10-09' ), array( 'clicks' = 1, 'clickDate' ='2010-10-08' ),);$pa
方法一:
<?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!
方法二:
例如:
<?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' ), ); $size = 3; $pnum = ceil(count($arr_click) / $size); if(isset($_GET['page'])){ $page = intval($_GET['page']); $page = $page > $pnum? $pnum: $page; $page = $page < $pnum? 1: $page; }else{ $page = 1; } for($i = 0; $i < $size; $i++){ if(!isset($arr_click[($page - 1) * $size + $i]))break; echo '<pre>'; print_r($arr_click[($page - 1) * $size + $i]); echo '<br>'; } ?> <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>
