Symfony vs. Phalcon vs. Fat-Free

Symfony is written with speed and flexibility in mind. It allows developers to build better and easy to maintain websites with PHP. Symfony can be used to develop all kind of websites, from your personal blog to high traffic ones like Dailymotion or Yahoo! Answers.

Phalcon is a web framework implemented as a C extension offering high performance and lower resource consumption.

Fat-Free Framework makes it easy to build entire Web sites in a jiffy. With the same power and brevity as modern Javascript toolkits and libraries, F3 helps you write better-looking and more reliable PHP programs.
