Kind of a nice solution for the problem I originally had which was to
use a list of categories in the db which had to be used in href for
pages with the same names. I had to sort the list as, at the time, I did
not know how otherwise to sort the list - the id field was not
sequential and I don't remember what other problem may have been
involved. I had forgotten that the sort changed the keys.
Actually, in the present case I did not want to sort by id since it was
already sorted the way I wanted.
Thanks to all for the input. The haze slowly clears... :-)
