Like Radius requests, each response may contain zero or more attributes. After a response has been received successfully by radius_send_request(), its attributes can be extracted one by one using radius_get_attr(). Each time radius_get_attr() is called, it gets the next attribute from the current response.
Returns an associative array containing the attribute-type and the data, or error number <= 0.
