That is no way to store data - there's no real identifiers for sub-lists. Also
- is this a hash (associative array) in PHP? I'm trying to figure out what's
your key here and what's your value. If the first number is the key, a simple
sort of the keys gives you your second list.
E-mail me on-list or off-list with some more info about what your data
structure is, and I'll run you through what to do.
