Mobile phone user interface for real estate website

I have a real estate web site (php + MySQL). I need to develope a mobile phone user interface. When the user access the web site, the system has to check if the user is using a mobile phone or a PC: - if the user is using a PC the system will show to the user the actual pages of the website ([login to view URL]) - if the user is using a mobile phone, he will navigate the website with special pages (mobile phone UI) What the coder has to do: 1) write the function that allow the system to check the user platform 2) write the mobile phone pages: a) home page with last 5 offers, with thumbnails and short informations, with next-previous buttons at the top and the bottom of the offers list b) a search form, that allow the user to search what he need ## Deliverables The coder can work directly on our web server, in order to semplify his work and reduce the developing time.
