As a ballpark estimate, I'd say that the above should be possible in under 100 lines of PHP code. You are looking at creating a Question class, an Answer class and a Visual/List class. The net result being that you double the number of PHP files and considerably increase the amount of code, there isn't much opportunity for code reuse here. Now, if the objective is to play with php OOP then go ahead. I would even suggest a DB class, a TableRow class, the Question and Answer then inherit from the TableRow, a TableRows class from which your List class would inherit. Maybe throw a few in to control the templates etc. as well. If the objective is just to get the job done and the site out, I don't see why you should bother with OOP at all.
