Re: QUESTION: how to validate credit card number before sent to Versi gn?

Look at the strings section of the PHP online manual. The function of choice is probably something like str_replace(). Not sure if this is the correct thing, but I know you can do what you want with a PHP string function. Good luck and make sure to keep those damn CC numbers nowhere on your machine.
