integrate Authorize.net

My website is a php website. I need some help integrating [login to view URL] into our order page. Specifically, We want to use CIM to capture the customer's credit card for future processing (We rent stuff out so we have to wait for the return and then we charge them) We've got all the gui etc. handled. But what I need is for you to build me a php function that will take an array containing the customer information and return back either: array(true,the trans ID) on success or array(false, ErrorCode) on failure. The input of the function would be an array of (name, addr, city,... cardType, card#, CVV2, Expiry Date)
