I have finished development of a PHP Class for managing Authorize.net Automatic Recurring Billing (ARB) transactions. The code and description have been published on the PHP Classes website.
Direct link: http://jbettigole.users.phpclasses.org/package/4666-PHP-Manage-recurring-payments-using-Authorize-net.html
The intended use for this class is to handle the addition, modification, and removal of recurring, subscription-based transactions through the Authorize.net payment gateway.
This class requires PHP 5
