How to delete a file from the server?

Question

Yii

Hello!
I ran into such a problem: I have files that I added to the folder myself and they are safely deleted using actionDeletephoto, but if I upload a file using actionCreatephoto, then only the entry from the database is deleted, and the file remains on the server. Please, tell me how to solve this problem.
Controller:

protected function findPhoto($id)
    {
        if(($model=Photo::findOne($id))!==null)
        {
            return $model;
        }
        else{
            throw new NotFoundHttpException('The requested page does not exits.');
        }
    }

    public function actionDeletephoto($id)
    {
        $photo=$this->findPhoto($id);
        if(file_exists(\Yii::getAlias('@frontend').'/web/img/image/'.$photo->name))
        {unlink(\Yii::getAlias('@frontend').'/web/img/image/'.$photo->name);}
        $photo->delete();

        return $this->redirect(['photo']);
    }
public function actionCreatephoto()
    {
        $model = new FileUploud();
        $photo = new Photo();
        if($model->load(Yii::$app->request->post()))
        {
            $file=UploadedFile::getInstance($model,'file');
            $model->uploadFile($file);

            $photo->saveImage($model->uploadFile($file));

        }
        return $this->render('createphoto', [
            'model' => $model,
            'photo' => $photo,
        ]);
    }

model

class FileUploud extends Model
{
    public $file;

    public function uploadFile(UploadedFile $files)
    {
        $this->file=$files;
        $filename=strtolower(md5(uniqid($files->baseName)).'.'.$files->extension);
        $files->saveAs(\Yii::getAlias('@frontend').'/web/img/image/'.$filename);
        return $filename;
    }

Answer 1

Feel sorry for disk space?) Send files to AWS s3 and store it all there for a penny. And you don't have to delete anything.
