As was mentioned in one of his previous blog posts, Sebastian Bergmann has been working up his own PHP version of an aspect-oriented framework. According to this new post, he's already done some work on the project and has created a page with more information.
As I wrote earlier, I am not satisfied with the Current State of AOP for PHP and started to work on AspectPHP a while ago. Today I am going to share my ideas on the subject.
He gives an example of this kind of functionality, including a bit of code to illustrate. The example logs all method calls and, in this case, simply outputs them to the browser.
Unfortunately, he also mentions that, at this time, he doesn't have any code for the framework that he can release, but you can check out the site he's created for more information.
