Display block if not in a role

Just put together the following snippet that will return false if the user does not have a specific role.

Please note that you will have to include the <?php ?> tags when you add this to your block PHP textarea.

<?php
  global $user;
if (in_array('Admitted Student', array_values($user->roles))) {
  return FALSE;
} else {
  return TRUE;
}
?>
