Build a Website

Create a website where you can show articles with text content and images. user can login through facebook , and google. and can share any article on facebook or google. user can like an article as well. also i want one page where an facebook app is present and user can use that app and show share result on facebook. and on the same page there is "you may like our other apps" where 4 5 other apps are present. for article section i want something like below [login to view URL] but less messy. also categories present here nothing but a field in database which you can ask admin on creation time and then show articles according to query. for apps part i want something like [login to view URL] for apps part i just want one or two apps for now but it should be scaleble. Technology:- for now i want my site to be written in PHP , for database we can use mysql because most of the content is images and we can store images on CDN. I want API based design for my site currently. e.g seperate backend and frontend. but if you have any alternate suggestion i am open.
