Coding Framework
We will use a simple fusebox-style coding framework. You may already be familiar
with this style, but if you are not, it's easy to understand. Take a look at the following
figure. All requests will pass through a central controller??”index.php. Based on the
value of the "action" variable, it will include another file. This action-specific file will
carry out the business logic. At the end, the resulting XHTML will be sent back to the
user's browser. Layout design is defined mainly in the header and footer files.
