I'm new to php and I'm having a bit of problem with figuring this out.

I'm just wondering what the method is to get several select values to display

This is my html;
PHP Code:
  <p>Your favourite movie: <select name="movie[]" size="4" multiple="multiple">
option value="Batman">Batman</option>
option value="Ironman">Ironman</option>
option value="Twilight">Twilight</option>
And in my php file I have this;
PHP Code:
$movie= array($_POST['movie']); 
and to display it;

PHP Code:
<strong>Favourite movie = </strong> <?php echo "$movie"?>
It's all really basic as I've just started learning it. I did google it and try different ways but not sure why it still isn't working.

Any help on this will be high appreciated. Thanks!
