MySQL STRING functions for BINARY formatting

I want to display a 32-bit integer as binary, but formatted to have a space every 4 chars.
I assume we start with BIN(FieldName), but what's the best way to insert spaces (or commas) every fourth resulting character?
INSERT?  REGEX?

thanks!

Do you have a programming language to work with, eg PHP? The formatting part is probably more easily done through something other than MySQL

yes but this is a "phrase" that goes into an app that generates PHP&MySQL code.
Thus it needs to be encapsulated (albeit lengthy!) for a SELECT query.
i understand PHP would be easier, but really need it in MySQL.
There are brute force strategies to mask&shift for each 4 bits to display, but i was hoping for a clever REGEX or other tricky way :)
I could even do four groups of 8 bits, if the code is really ugly.

thanks

... or maybe it's just a series of  
CONCAT(
   LEFT(BIN(FieldName),4),' ',
   MID(BIN(FieldName),5,4),' ',
     ...
   )

I think that's probably the best you can do. Regular expressions in MySQL are only capable of saying "yes that matches" or "no it doesn't".
