Android client-server model

Question

I'm implementing a client-server model for an online store. Basically I need to retrieve from the server some information like the things the buyer brought (price, description,link, self & other users comments about the article etc) showing it in the device, allowing to navigate thought the catalog, and comment resending the updating info to the server. How can I implement that? I have thought in a web server with php+mysql for the server, querying through html post and generating the php answer as a xml with all the information needed. Is an acceptable solution? I really dont know how many potential user can this application have simultaneous but it could become pretty high.

Thanks in advance

According to me, what you're currently doing is pretty acceptable.
We call it WebServices
