Conditional restrictions: ipad calls PHP (website), PHP calls Aspx (website), and Aspx calls WebSErvice (website)

Php has implemented the call to aspx (post transfer), but how does aspx return data to tell php whether the execution is successful or not?

Php with online copy calls aspx implementation, but I don't know how to write the aspx page to return a data to php. Please advise
