title: Calling web service (SOAP) with PHP involving enums
body: <p>I wish to call a web service, using SOAP, from PHP (using the included SOAP extension). The web service in question is <a href="http://www.webservicex.net/CurrencyConvertor.asmx" rel="nofollow noreferrer">http://www.webservicex.net/CurrencyConvertor.asmx</a></p>
  
  <p>Now the Currency type is an enum, and I cannot figure out how to work with these in PHP in order to be able to call the 'ConversionRate' function. I know I have to do something with a class map, but I can only find limited and unhelpful information on this topic. Can anyone help? A working example maybe? </p>
  
  <p>Thanks!!!!</p>
