Gonzalo Ayuso has a new post to his blog looking at some of the recent work he's done with PHPDoc and annotations to create "function decorators" in his code.
The idea is to solve the same problem I had when I wrote the previous article. I want to protect the execution of certain functions in a class to only being executed if the user is logged on. [...] The solution with interfaces is clean and simple (no extra libraries need and no reflection need too). The problem is that I can use it only for all the functions of the class.
He gives an example class with four different methods (one with annotations) and his annotation parsing class that runs the predispatch and postdispatch methods based on those annotations. He also shows another examples using an abstract class.
