Question

how to call a C# .NET web service from a php client

Answer 1

+1 A:

Assuming it's a SOAP web service, you should just be able to use the normal php SOAP library. Now SOAP portability isn't quite everything it's cracked up to be in my experience, so you may need to fiddle a bit (in particular, test things like how empty arrays work) but that should be a good starting point.

The docs I've linked to look pretty good, but if you search for "php SOAP tutorial" you get lots of hits which will take you through step-by-step.

Another option is nusoap. I can't comment on which implementation is better.

Thanks. I thought of using nusoap

Answer 2

+1 A:

Since PHP is a dynamic language, its pretty straight forward. All you need is a library (SoapUI) and the WSDL. If you have the location (URL) of the web service add a ?WSDL to the end of the URL and you have the definition. Then its just calling the service from there.

<?php
require_once('libs/nusoap.php');
$wsdl="http://thedomain.com/theservice/endpoing.svc?wsdl";
$client=new soapclient($wsdl, 'wsdl');
$param=array('number1'=>'2', 'number2'=>'3');
echo $client->call('add', $param);
?>

You can find the library here: http://www.soapui.org/

thanks. I have the url of the web service and I installed soapui as well. Can I know what did you mean by require_once('libs/nusoap.php') ?It can't find the path 'libs/nusoap.php' and gives the following error.Failed opening required 'libs/nusoap.php' (include_path='.;C:\php5\pear') in C:\wamp\www\hello.php on line 6

I got it. I m using nusoap as the soap client library. I tried to call the HelloWorld method of the web service using following: require_once('lib/nusoap.php'); $wsdl="http://localhost:64226/Service1.asmx?wsdl"; $client=new soapclient($wsdl, 'wsdl'); echo $client->call('HelloWorld');But it does not return the output "Hello World". Instead prints the word "Array". Any idea ? I know this must be a very basic question i m asking :)

Sorry, I'm used to PHP4, so an even better solution for you if you have PHP5 is to use the built in SoapClient. Example code (tested) runs like so:[PHP Client]<?phpclass SayHello { public $name = 'Benny';}$client = new SoapClient('http://localhost/WebService1/Service1.asmx?wsdl');$result = $client->SayHello(new SayHello());echo $result->SayHelloResult;?>[ASMX Service][WebMethod]public string SayHello(String name){ return "Hello " + name;}

thanks a lot Benny! It worked for me using SoapClient in php 5. Initially I got an error saying it is undefined and then I realized that I had not enabled php_soap extension in WAMP. After enabling it worked :)
