Well,
Finally the wait is over. Black iD is into the final testing of the class we have been working on for the last 6 months. We are running it through the phpDocumentor and trying to make the best for you all. The next releases have been planned already. We will be fully supporting the current release in the next one. So we hope you enjoy this class a lot. The code for this class is available here. We will try to expand this class even more.
Another excellent news is that we are now registered as the developers at PEAR website. We are proud to be supporting a community that has worked so hard thus far to keep up the spirits high. We will try to contribute in each way we can to come up with the best pieces of code. For now please accept this beautiful piece of code
