God I LOVE you guys! lol
That's the exact term I needed - cartesian product. Simple google
search got me exactly what I needed.
AHHH. I could hug you all! :D

(cartesian product)
There's a few implementations around the net, I'd be surprised if there
isn't one for PHP.

So you basically want a cartesian product of an arbitrary list of lists?
The Ruby facets gem does that:

Heres what the Ruby code looks like (works for an arbitr
I think Mark's answer was correct given the example you initially gave. However, if you want to iterate over groups of dissimilar sets without hard coding the looping to a fixed 'n' then I think you're after something like a multi-dimension iterator.I wrote one for Java here: http://www.alexpooley
without knowing PHP or your data structure ... can you build an array
of arrays, option group x option? Recursive iteration through the
arrays can work then

OK ... so how many option groups? are they variable? what language are
you trying to express this in?

Hmm ... what idioms are we allowed then? :-)
Iterate over the sizes
within each size
iterate over the colours
make a combination and stow it somewhere
Does that make sense?
Either that or get some sleep :-)

This may seem rather simple to some, but being late at night it's
driving me up the wall..
The context behind this is I'm trying to create all unique product
options for a product.
Consider:
We have two product option groups, size and colour.
Size contains: S, M, L, XL
Colour contains: red, bl
The problem was that I had Rack 0.9.1 as a dependent gem in my
environment.rb which conflicted with the version of Rack that is
bundled with Rails 2.3.2. I had added rack 0.9.1 as a dependency
because Rspec 1.2.2 needs it. I moved the Rack dependency to test.rb
and now everything works.
