A bare-bone illustration of how a PHP Web Service is created using SOAP (Client/Server). The first part covers all the necessities that will get you a base that can be used to develop whatever you want to do with it.
However, the second part will deal with sending Headers and issuing Authentication through that.
If you have any questions, feedbacks, suggestions, plz feel free to let me know. If you have any requests about other topics you want them covered, then just mention them and I’ll make a Tuto about them, hopefully soon.
