documentation

Hi,

 

I am new to the list and to nusoap.  Where can I download a zip file with the latest documentation for nuSoap?

 

I have already written a few simple programs to use the soapclient class.  However, I am at a loss as to how I can understand a webservice just given a WSDL file.  After I create an instance of the soapclient class with the address of the wsdl file is there a way for me to now see :

 

1) What functions are supported in the service

2) What parameters each function takes

3) What does it return

 

Anybody written a simple test program in php to walk through the parsed wsdl file and list the above.  From my basic understanding of WSDL files, is that they provide a view to the webservice's API.  So that anyone can use the webservice just by understanding the WSDL file.

 

Thanks

Ravi
