you cannot do credit card processing in phpdirectly... you have to have php collect the infromation and send it off to a company who will do it for you...

verisign has payFlowPro... so if you have an account that uses verisign to do your credit card processing you can install the php library which talks to the payFlowPro library... and from php you can process credit cards....

you will however need an account that can accept online payments and credit cards... a merchant account...

read up about it on verisign... there polenty of companies that will manage this for your... most are just wrappers for the verisgn libraries that you could do yourself with some research...

sounds like you will probably want/need a company that does credit card verifictation. how you write the code to submit it to them usually depends on what company you use for the validation

credit cards usually use the luhn formula to calculate a checkdigit, so you can yourself usually validate whether a number could potentially be a real credit card number, but not that it actually belongs to someone.

also each different credit card company has a different set of digits that their cards begin with, so it is also possible to determine which company issued the card.

but to actually verify the card belongs to someone you will need, as i said in the beginning, a credit card verification company and how you submit the number to them can vary.

here is a class that validates that a particular number could potentially be real. zend

Alternatively, you don't need to do "online" credit card processing. You could verify that it's a valid card number in php, and then just save the information securely until you have a chance to manually "ring it in" through a normal credit card machine. You still need to have a special account for charging credit cards without actually handling them, but you don't have to worry about the headache of transfering information to other companies.
I'm no expert on the subject, but from my knowledge it's not worth the money and effort to do online processing through third party companies unless you plan on having high sales. 🙂
