PHPLibs is a set of php libraries that can help to easily develop a php site without relying on strict and complex frameworks. It was originaly developed to create the kmfa.net. but it was released to the public to help anyone that does not want to learn a complete framework. You don't even need to use all the libraries together. For more information look at API reference or download them.
To make it easier for the starter an example site was created that can be downloaded and start expanding it. This is like a skeleton to start building your own site using phplibs. Skeleton site can be found at download section.
