"HipHop for PHP transforms PHP source code into highly optimized C++. It was developed by Facebook and was released as open source in early 2010."Much to my surprise, tonight, I downloaded, configured, installed and tested. It all worked, first pass. No tinkering, no nothing.
Second, I took the most complex PHP project I have, with lots of different dependencies and pushed it through. Guess what?
It works. It really works.
