New ability to usergroup > genericoptions

[Robert9]

I need a new ability for some of my groups, now i could do it with a new field in the usergroup table or i can use the generic options. For this i need "convert_array_to_bits" in "function_misc.php".

What i dont know is how this function works, normaly i use:
select 1 = 1
select 2 = 2
select 3 = 4
select 4 = 8
and so on, with this i got the sum.
Example select 1 and select 4 makes 9, but this is only functional if i know the sort of my selects. With the code i found till now, there is nothing about this sort.

Has someone do this before and now the right places to look for the code?

Ok, found it. It is in includes/init.php ;-)
