Yii中CArrayDataProvider和CActiveDataProvider的区别有哪些?
本文实例讲述了Yii中CArrayDataProvider和CActiveDataProvider区别。分享给大家供大家参考,具体如下:
1、CArrayDataProvider
获取其他数据库或者数据表的数据列表
$sql = "Select * from tbl_count2 order by id desc"; $data = Yii::app()->marketdb->createCommand($sql)->queryAll(); $dataProvider = new CArrayDataProvider($data, array( 'pagination' => array( 'pageSize' => 16, ), ));
2、CActiveDataProvider
获取当前model的数据列表
$dataProvider=new CActiveDataProvider( 'PhotoAttachment', array( 'pagination'=>array('pageSize'=>20), 'criteria'=>array( 'condition'=>implode(' and ', $condition), 'order'=>'id DESC', //'with'=>array('author'), ), ) );
希望本文所述对大家基于Yii框架的PHP程序设计有所帮助。
