Retrieve image from Folder - without knowing extension

Hi ,

i'm storing an image in my public/image folder through the upload function .

For the upload , its easy to get the extension : ->getClientOriginalExtension()

However now i want to retrieve that file ...i know the name but i don;t know the extension (jpg , png etc...)

how can i retrieve that file ?

        $folder = base_path() . '/public/image/';
        $name ="yyy";
        
        $path = $folder.$name;
        
        // does not work as i'm calling this on a url rather than the file
        $img_type = $img_path->getClientOriginalExtension();
