Actually, Facebook has a compiler that transforms PHP source code into C++ [1], and they claim a 50% reduction in CPU usage. It's an interesting approach, though I suspect that even as we speak a new circle of hell is being warmed up especially for those who are enabling PHP's continued existence thanks to gimmicks such as this one...
