As long as you do not post a concrete question pertaining to mysql you probably won't get an answer.
If you rather do your processing in PHP or in the database is a matter of taste, speed and efficiency. I recommend that all processing which can be moved to the database should go there because then it does not matter if you use PHP or any other interface for data manipulation.
Furthermore your problem seems to be solvable by a (maybe complicated) query. But that is impossible to say without data structures, test data and desired results.
