Change:
<select name="notify_user_id[4]"
to:
<select name="notify_user_id[4][]"
Notice the extra [] after the name. So, on the page that processes the
form, you'll have $_GET['notify_user_id'][4] and it will be an array:
foreach($_GET['notify_user_id'][4] as $notify_id) {
//do something with $notify_id
}
