How to save file from server in Yii2?

Question

Yii

Hello. There is a link called "Upload to dbf". It leads to the controller that generates the dbf file and puts it in the archive. The archive appears on the server in the web folder. How to download it now? Is there a way to get the link back?
I tried something like this, nothing happened: ps. I am new to yii.
return Yii::getAlias('@app/web/'.$this->file_zip);

Here is another method for Yii2

<?php
public function actionDownload() {
   $path = \Yii::getAlias('@uploads') ;
   $file = $path . '/some-file.pdf';
 
   if (file_exists($file)) {
       return \Yii::$app->response->sendFile($file);
   } 
   throw new \Exception('File not found');
}
