about SOAP and Nusoap

[eluser]mztest[/eluser]
Today I searched the keyword "soap", many results is about "NuSoap".

Is nobody use soap on CI in directly?
why?
what's the different between them?

Now I need use soap to make api for mobile application.
what I should use? soap (php5 include this) or Nusopa?

I've only used SOAP a limited number of times, but I've had no problems with PHP's Soap extension. If you've got it compiled into your PHP configuration, I recommend using that...
