Here is a small patch against version 3.0.6 (*NOT* against trunk) that

The original problem is that ctype_digit is literal in what it checks
for: digits. So "4" would get passed, but "4.0" would not, since
that pesky non-digit "." character is there. We actually want valid
numbers, not just digits. is_numeric should work here, or some fancy
regex (but that's probably slower and not needed).
