Answer 1

For Drupal 7 you can use path_is_admin() .

if (path_is_admin(current_path())) {
  // Do stuff.
}

For Drupal 8 isAdminRoute()

$is_admin = \Drupal::service('router.admin_context')->isAdminRoute();
if ($is_admin) {
  // Do stuff.
}

I don't fully understand your end goal, but here are two answers to your question:

1) if (arg(0) == 'admin') { ... } will indicate if someone is in the admin section, since the entire admin section has paths prefixed with admin/

2) At admin/settings/admin/theme you can select a separate theme for the admin section, and then you'll know someone is in admin when that theme is loading rather than the main theme.
