This is a list of my favourite libraries and tools. I can recommend any of them without doubts.
- AngularJS – IMHO the most clean way to work with JS in a web application
- Gaufrette – Gaufrette is a PHP5 library that provides a filesystem abstraction layer
- Imagine – The best php image manipulation lib, really
- Omnipay – An easy to use, consistent payment processing library for php.
