本文实例讲述了yii分页组件用法。分享给大家供大家参考，具体如下：
该案例使用时，分页类在yii框架中以组件的形式存在于components中。
action代码如下：
|
1
2
3
4
5
6
7
8
9
10
11
|
public function actionIndex(){ $user=User::model(); //分页的使用 $count=$user->count(); //获取总页数 $pagesize=3; //每一页显示的记录条数 $page=new Page($count,$pagesize); $sql="select * from {{user}} $page->limit"; $info=$user->findAllBySql($sql); $show_page=$page->fpage(); $this->renderPartial("index",array("info"=>$info,'show_page'=>$show_page));} |
在view页面，遍历info即可获取信息，输出show_page即可显示分页列表等信息。
现附上page.php代码如下：

希望本文所述对大家基于yii框架的PHP程序设计有所帮助。
