I don't see the problem with the code. you're testing for the values… so you just need to specify what to do if the requirements are not met.

something like
Expand|Select|Wrap|Line Numbers
  1. if (in_array('other', $_POST['hobbies']) and !$_POST['other'])
  2. if (in_array('other', $_POST['hobbies']) xor $_POST['other']) // should also work
