// I don't want others to go through the same problems, so I am submitting this example script
// This script will work with Authorize.net's AIM method of processing.
// This code has been heavily borrowed from several sources.
// It requires a server that supports PHP and cURL.
// If you have any comments, please contact erik@grossmontdesigns.com
// From a previous HTML Form, pass the following fields:
// $FirstName = Customer's First Name
// $LastName = Customer's Last Name
// $CardNum = Customer's Credit Card Number
// $Month = Customer's Credit Card Expiration Month (Should be 01, 02, etc.)
// $Year = Customer's Credit Card Expiration Year (Should be 2003, 2004, etc.)
// $Address = Customer's Address
// $City = Customer's City
// $State = Customer's State (Should be 2 letter code, CA, AZ, etc.)
// $Zip = Customer's Zip Code
// $Email = Customer's Email Address
// $cost = Total Price of purchase
// Check to make sure customer entered all relevant information
