我的模型FAQ有4个属性
* @property integer $id
* @property string $chapter
* @property string $question
* @property string $answer
现在我的actionIndex函数看起来像
- public function actionIndex()
- {
- $faq = Faq::find()->all();
- $dataProvider = new ActiveDataProvider([
- 'query' => Faq::find(),]);
- return $this->render('index',[
- 'dataProvider' => $dataProvider,'faq' => $faq
- ]);
- }
如何在Controller中使用Yii2或PHP获取$chapter的唯一值数组?让我们说在sql看起来像
SELECT DISTINCT chapter FROM’faq_table’
