Continuing on from the first part of their tutorial series about creating a simple ad tracker for your web application, Developer Drive is back with part two, a more in-depth look at the actual object design and code.

In our last PHP Ad Tracker lesson, we constructed the database tables for our ad banner application. Now we are ready to construct the data object that will hold the variables and functions that will display, add, edit and delete the data in those tables.

They cover each of the variables they'll be using with a summary of what they're used for as well as the various functions to be defined and what they'll return. Following this, they get into the actual development - creating an "ads" class and defining the methods to get the current ad count, get the number of clients and pull the actual client/ad data.
