I recently created a simple PHP software development framework named Nolkode, and just released it. I hope someone can find it useful. Please visit this link (currently Nolkode is hosted at my personal website):

Nolkode can be used to develop free or commercial/proprietary application. It is licensed under BSD license.

Best regards,
