PHP SOAP tutorial? [closed]

[siemens01]

I need to write a SOAP client using PHP 5.3. The WSDL for the service is reasonably complicated.I can't find a PHP SOAP tutorial anywhere that walks through how to do this - I haven't found any that use the 5.3 SoapClient and explain how to construct SoapVars and SoapParams for complex data types.Is this the best library to use? I'm assuming it must be for speed. I've seen a lot of references to nusoap which I'm assuming was the library most people used before PHP got its own native libraries.Does anyone know where I can find a tutorial to help please?Thanks
