在无脂肪框架中,重命名后如何获取上传的文件名?

我用这个来保存上传的文件

$web = \Web::instance();

$uploadPath=$f3->get('uploadFolder');
$f3->set('UPLOADS',$uploadPath);

$overwrite = true;
$slug = true;

$files = $web->receive(function($file,$formFieldName){

        if(file_exists($file['name'])){
            //$file['name'] = $f3->get('uploadFolder').'rename.jpg'; // this is error, how to get path from config.ini here?
            $file['name'] = 'assets/img/upload/rename.jpg';
            move_uploaded_file($file['tmp_name'], $file['name']);
            return false;
        }else{
            return true;
        }
    },
    $overwrite,
    $slug
);

$savedFile=array_keys($files)[0];

这只获取重命名前的文件路径,如何获取重命名后的路径?
