Refactoring a large legacy PHP Application: a case study

In recent months I have had the opportunity to work on the refactoring of a large legacy application, for a good part written in procedural code: the challenge was to make the application evolve to keep up with the business needs, without embark on an expensive and unthinkable rewrite During this session I'd like to share what techniques we used to achieve the goal, highlighting what worked well, and what didn't, to give you a couple more ideas the next time you're facing a similar challenge. Some of topics: - code organization from folder structure to classes - choosing an architectural style - testing - refactoring to objects
