Duplicate code is one of the most pungent code smells. A rule that is often used is to re-structure code once it is duplicated in three or more places.
Common duplication problems, and corresponding solutions are:

This check looks for classes that have been defined more than once.
If you can, we would recommend to use standard object-oriented programming techniques. For example, to avoid multiple types, it might make sense to create a common interface, and then multiple, different implementations for that interface.
This also has the side-effect of providing you with better IDE auto-completion, static analysis and also better OPCode caching from PHP.
