Yii2 How to store multiple values ​​in a linked table?

Question

Yii

Good afternoon.
I started to learn Yii2 and I can't figure out how to store multiple values ​​in an intermediate table.
At the moment, I save via link(), but as far as I understand, only 1 value can be saved this way.

public function actionUpdate($id)
    {
       $model = Hosts::findOne($id);
        if ($model->load(Yii::$app->request->post())) {
            $hosts = Yii::$app->request->post("Hosts");

            $platforms = Platforms::findOne($hosts['platforms']);

            $model->link('platforms', $platforms);

            $model->save();

            return $this->redirect(['view', 'id' => $model->id]);
}
