BIGSTORE started out as a personal project to learn how about managing temporary variables that was invisible to the user. As time progress, a friend of mine saw the potential and had me develop it into a shopping cart. As time went by, it turned into the most extensive project I’ve ever worked on. As I learned more in PHP, I applied that new knowledge to a module of the store. It’s got an extensive backend/admin to it and configurable to support more than one site within the same database.
