I have a web form where people enter their address info and I want to
make sure that the first three digits of their Zip Code correspond to their
State.
So I'm creating a hash of arrays that contains a list of Zip Codes for
the United States. I've also written a foreach loop to access this hash but
I'd like to see if it could be written better. For example, do I really need
three foreach loops?
Also, the first line that's printed contains "499" and I can't figure
out where that's coming from.
I'd appreciate some help.
Thanks,
Marc
