                if($key != $data['download_key']){
                    echo 'Your key is wrong.';

                }
            }

You forgot to wrap string with quotes in alert .

“Your downlaod key is wrong, Please try again!” is a string

if(isset($_POST['downloadkey'])){
                $key = $_POST['downloadkey'];
                if($key != $data['download_key']){
                    echo 'Your key is wrong.';
                    echo '<script type="text/javascript"> alert("Your downlaod key is wrong, Please try again!");</script>';
                }
            }
