In this case study, we will develop a web-based shopping cart application for mobile devices using PHP. This application will allow users to access the shopping site from their mobile devices (mainly phones). Most of the cell phones available in the market today have a built in Wireless Markup Language (WML) browser. Users can browse different WML sites (for example, http://mobile.yahoo.com/home/), using the browser.
In developing this application, we will go through the complete life cycle of software development. We will go through the following steps:
Identifying requirements
Choosing the right products and programming language for implementing the application
Designing the application
Implementing the design
