[PHP] for all you recursion experts--i'm stuck! help! From: Bill Zeller (billzeller <email protected>)

Hey,

I've been trying to figure out how to loop through a
"box" of letters. For example, if I had something like
this:

 a d b a e t b
 q a w e g a w
 w b p w a e d
 p a w e d g p
 d a w w e b a

It should start at a and loop through every possible
combination until it finds out that it can't be a
word. So in the above example, it should think like
this:

1. There are words that begin with a, continue...
2. 'ad' is a word, add it to array $words[]...
3. There are words that begin with 'ad', continue...
4. 'adq' is not a word, do not add it to array
$words...
5. There are no words that begin with 'adq', go back
to last word (in this case it is 'ad')

It would then go onto adb, adba, etc. It should loop
through every possible combination the entire puzzle,
checking each letter with every other letter close to
it.

Any ideas on where to start?

Best Regards,
Bill Zeller
