How to upload files in Yii2?

Question

Yii

I'm trying to upload a file in Yii2, but it doesn't work. I did it according to the principle of loading an image

public function uploadFile()
    {
        if ($this->validate()) {
            $path ='upload/store/' . $this->file->baseName.'.'.$this->file->extension;
            $this->file->saveAs($path);
            $this->attachImage($path);
            @unlink($path);
            return true;
        } else {
            return false;
        }
    }

Well, your path is clearly not complete. You need to specify the full path. For example:
and I don't quite understand why you delete it immediately? And if so, what are you expecting?
