Is this search code safe? Are Sql injections possible?

Question

Yii

I want to implement a secure search on Yii2, yii\db\Query with a prepared query is not very suitable since there is a lot of related data and you will need to use join in many places, since after the search I will display a lot of related data. The question is whether such a simple method is safe code below :

if (Yii::$app->request->isPost){
            $search = Yii::$app->request->post('search');
            $search = Html::encode($search);
            $shops = Shop::find()->where(['Like', 'name', $search])->orWhere(['Like', 'address', $search])->all();
}

Here is part of the code

Answer 1

Safe)

Answer 2

This is not necessary:
$search = Html::encode($search);
​​, this is only when outputting to the browser
