This is python interactive mode operations.

Quote the keys to the value again.

Take number 280. This is 256 + 16 + 8
                  = DontReceiveDuplicates
                    + ConcealSubscription
                    + DisableMime
So the member doesn't want receive list mail if his address is in Cc: 
list, not want to list his address in the roster page, and he want plain 
text digest if he move to digest mode.

264 = 256 + 8 = DontReceiveDuplicates
                   + DisableMime
Similar to above but this member doesn't care if his address is listed 
in roster page.

314 = 256 + 32 + 16 + 8 + 2
                = DontReceiveDuplicates
                  + SuppressPasswordReminder
                  + ConcealSubscription
                  + DisableMime
                  + DontReceiveOwnPosts
This member doesn't want to get monthly password reminder, and doesn't 
want to receive his own posts adding the options of the first member.

There should be many combination of numbers which indicate 'hide' status 
but there is a nice operation to get this; 'bitwise and'. So, if you get 
members subscription status code in say member_status, then you should 
write a program like:

if member_status & 16:
     print 'Hide this member.'
else:
     print 'Expose this menber.'

This is Python code and not PHP in which you are wirting, but the logic 
should be clear. You can refer to the php '&' operation manual at
http://www.php.net/manual/en/language.operators.bitwise.php
(After quick googling).

Cheers,
