So I’ve had quite a bit of experience with authorize.NET and PHP and I’ve found it’s difficult to find resources that provide textual examples for integrating the payment processor. I’ve put together a generic tutorial from Authorize.NET documentation that is public. Of course, you will have to specify your Transaction ID and API Login ID. So here you are.

The example that Authorize.NET provides does a lot of parsing through strings. I prefer working with arrays as they are easier to read, shorter to write and from what I understand, faster to parse. Also, I like to organize my data in classes. For this example, I’ll just show the function as that should be enough to integrate.
