Payment gateway integration

I would like to add a payment module on my website that I`m going to build, I want the users to pay mainly using Credit Cards, Master Cards or Visas. It would be good to also add PayPal payment, any other method will be acceptable.

If there are tutorials for the installation of the module would 开发者_如何学编程be great.

PS: I don`t mind paying for the usage of the service.

All the major merchants (PayPal, Google Checkout, Authorize.Net, etc.) will have integration capabilities with PHP. For example, here's some sample code for Authorize.Net.

Most payment gateway providers provide developers with documentation on how to integrate their gateways in a plethora of languages such as PHP, Java, .NET etc.
