EasyPIBA is a lightweight PHP framework, easy to install, easy to learn, easy to develop.
PIBA stands for PHP (just because), InnoDB (yes, InnoDB with relations between tables, so you don't have to write code for interacting with the database, and that's very cool), Bootstrap (because it's cool) and AdminLTE (because it's also cool).
So, if you want to save time and energy you should give it a try. Right now. Trust me. It will cost you 2 minutes to install if you have git on your machine or 5 minutes to download a zip file and unzip it, plus 2 minutes to go trough setup. Sounds easy and fast, isn't it?
