i need to develop a web-page for a small company about credit card transaction when users buy its products on the internet.
my questions are:
1. are there php code samples about securities of transactions? i.e. encoding and decoding of card's number?
2. how to confirm if a credit card is valid or invalid? any code?
3. are most of credit card transactions on the internet using php tech currently?
this is my first post, hope to get help here.
many thanks
need your suggestions for credit card transaction

It all depends how the company does charge the credit card. I would recommend using a 3rd party company that has experience with fraud scrubbing and chargeback avoiding. You will most likely not be able to creat a system that will be working for the company as online credit card transactions require a very sophisticated approach.
That said if you google for 'credit card validation' you will find the code to verify if a valid number is used. Given how easy it is to get that code you can imagine how far you can trust a number given to you online.

u r right.
i have contacted with 2 3rd party companies.
"regnow" charges 16% but if the credit card is invalid, the company still charges me 16%. i think it is not fare because higher fee for the service should get higher securities.
"paypal" charges much less but payers must log-in as their customers, i think payers don't like complex payment process - at least i never pay anything in this way, i don't like it myself.
do you know other 3rd?
thx

I've used paybycash/sabercharge in the past to great success, although I don't remember their policy on falsified card numbers and stuff..

I used Authorize.Net and PayPal. i like Authorize.Net more though than PayPal because of its easy integration. 
authorize.net is the way to go. They have an advanced integration method (AIM) that you can use to submit people's card numbers to their site w/o leaving yours and it returns information about the validity of the card which you can display on your page.
You WILL be required to have a merchant account (unless they've changed things in the past 6 months), but your company's bank more than likely offers that service.
they offer service at a monthly flat fee of ~$20.00. (this does not include the credit card companys' chunk which ranges from 2.5 - 6%).
creating the AIM side on PHP is a piece of cake and I'm sure there are a million code samples out there...google it. If you can't find one, I'd be happy to help you out with that part.
