Using SoapClient on the Client side

I have been researching a case where a gentlemen used Soap Client, to gain access information from a server. He is claiming he used these as the client, and I am curious how that is. Or just discussion on the idea.

This is his article, the 3rd and 4th photos are right under where he claims he sent the request to his server. So PHP soap Client as I understand it is something used by the developers and on the server side, so if that is true, how is he able to do this.

Any clarification or discussion is greatly appreciated.

1st post by the way!!! wooohooo! haha
