I’ve complained a lot when I worked with PHP about PHP’s terribly inefficient design; I’ve complained about it, just because it was PHP. The things I missed most in PHP, it seems, were actually there all along!
One reason PHP really sucked was that you need to load small data from and to databases or files if you want to share it between page views. The whole concept of handling a request per page view is ridiculous too, IMO.
With those two libraries however, PHP pages could be way more efficient.
I wonder why the big PHP software haven’t used it. Lets hope it isn’t portability.
