From Tutorialzine.com today, they've posted the first part of a series looking at the construction of a full mobile website using PHP, MySQL and jQuery mobile.
In this two-part tutorial, we will be building a simple website with PHP and MySQL, using the Model-View-Controller (MVC) pattern. Finally, with the help of the jQuery Mobile framework, we will turn it into a touch-friendly mobile website, that works on any device and screen size. In this first part, we concentrate on the backend, discussing the database and MVC organization. Next time, we will be writing the views and integrating jQuery Mobile.
Their simple application lets you browse products in a storefront with products and their categories. They don't use any particular framework and instead opt for a "include all" approach in their example. This makes it simpler to bootstrap, but shouldn't be used in a production-ready version of the application. There's simple frameworks (like CodeIgniter out there that can help take it to the next level without much more complexity). You can see a demo of it in action or just download the source to get started hacking.
