Shoot...I hadn't considered how PHP might handle hex or octal strings when
casting to int. (Again, not in front of a computer where I can test it
right now. )
Regexes have problems with more than 9 digits for 32-bit ints. I guess to
some degree it depends on how likely you are to experience values that
large.
