Used __getFunctions() of SoapClient for my WSDL and I got same functions

PHP Code:

---

Array
(

   [0] => AirRepriceRsp service(AirRepriceReq $parameters)
   [1] => FlightDetailsRsp service(FlightDetailsReq $parameters)
) 


---

I'm pretty sure that the function is service, but i got same functions from my wsdl.

Any hints please.

Thanks.
