When used in this case, the paging class exists in the form of components in the Yii framework.

The action code is as follows:

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));
}

On the view page, traverse info to obtain information, and output show_page to display the paging list and other information.

The page.php code is now attached as follows:

<?php
/**
 * 分页类，以组件形式存在于componnets文件中
 */
class Page {
  private $total; //数据表中总记录数
  private $listRows; //每页显示行数
  private $limit;
  private $uri;
  private $pageNum; //页数
  private $config=array(&#39;header&#39;=>"个记录", "prev"=>"上一页", "next"=>"下一页", "first"=>"首 页", "last"=>"尾 页");
  private $listNum=8;
  /*
   * $total
   * $listRows
   */
