Re: Regex an Array?

you have a scalar (specifically a string), not an array
you've said what's valid, so check for the presence of anything that doesn't match (/[^\d\s,]/; \s because there's whitespace in your example)
alternately, go ahead and split on /,\s*/ and use grep to pick out (or exclude) the numbers (non-numbers)

It's important to note that `\d` can match characters other than the digits 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9, which is probably not desireable.	[reply] [d/l]
