PHP has built in functions for connecting to Payflow Pro. You should also contact Verisign for more information on integrating their gateway. They may even have sample code for you to work with.

You need to validate all of the data yourself. Verisign will just pass all of the information on to the processing bank which will approve or decline the transaction and then send it back to your to handle however you see fit.

You'll need to make sure the credit card is in a valid format. Same for the expiration date. You'll also need to verify you have a street address and zip (again, in the correct format) so AVS can be performed on the sale. If you don't the transactions will be declined if there is an error and the sale will be lost.

If you don't know how to integrate their gateway you should contact Verisign for help or hire someone with experience to do it for you.

yes i have done weather the creditcard is in proper format or not in javascript. the coding is not a deal. but i wanted is weather the credit card is not valid credit card or not. yes i got it when we connect to verisign it will do all acual credit card validation and send the money to my bank .and if it is bad credit give error message.i was little confused about SSL certificate but,in verisgn it is nicely explained.
for more info i will go throught verisign and they are offering 14days free trail also.thanks u so much
