That's just standard URI-encoding. If you access it in the normal way, it's decoded for you:

$country = $_GET['country'];

If you then want to change spaces to dashes, just do a replace.

$country = str_replace($_GET['country'], ' ', '-');

(If your form is using POST rather than GET, just change $_GET above to $_POST.)
