Can anyone explain me better the conpcept of the webservice. I'm using wamp for a school project, i'm creating an adress-book with JSON and AJAX. The Deitel's one if you have encounteered it before. I have the deitel's code and simply want to implement it in my website. It's requesting webserviceurl. The site i want to create is in php. I have attached the script and highlighted the things i don't understand.
Hope this explains it: In a simple sense, webservice is a standardized way for you to provide data and communication to your other software or a 3rd party software. Like in your php code and your js code, how will the js code understand your php code?
