C# webservice returns null which called from php

Question

Im calling a web service(C#) which generates a random number between (1 and 5) from php code using nusoap_client.The php code is as follows

$client = new nusoap_client('http://localhost/TestWebService/TestWebService.asmx?WSDL','TRUE');
//echo("execute". $client);
$result = $client->call('GenerateRandomNumber');
//echo("executerandomn".$result);
$return=redirectpage($result); //redirectpage() function redirects the user based on the random number generated.

The function GenerateRandomNumber() is returning null.I tried browsing the webservice separately its working but not when called through php.

The WSDL created is below

Please Help.

Build your webservice in a RESTful way, you can find a starting point petefreitag.com/item/431.cfm or xfront.com/REST-Web-Services.html. And here is a C# library which can be interesting : restsharp.org — Epoc

I've been a little bit sarcastic (sorry) : using SOAP can achieve your goal, but in my opinion SOAP is too heavy and too slow, I personally prefer using RESTful webservices. — Epoc
