I think you are assuming that the bit of code that converts PHP to JVM bytecode (and/or a Java PHP interpreter) is an insignificant chunk of engineering. Quercus has lagged PHP5 development, and it needs work in order to run common apps. Plus, an analog of the Ruby RSpec project will probably have to be built for PHP (PHPSpec?). The PHP5 implementation is the spec right now, just like Ruby (used to be). Quercus is currently a component of a commercial Java application server. Can Quercus can be run in another app server, like Jetty, or does it only work in Resin? I doubt that Caucho would be interesting in making Quercus work stand alone. Quercus will probably need to be forked. That is quite a lot of work. How many people did it take to create JRuby (Ruby on the JVM) and the RSpec project? From the mailing list, it looks like it was about 5 to 8 core developers over about 2 years. And then after all that, JRuby is still not the preferred deployment environment for Ruby (it's mod_rails aka Passenger). Though, RSpec did end up making the original Ruby implementation better. I'm not opposed to PHP on the JVM, but it is not a small undertaking. You should probably begin by extracting the Quercus code from from the Caucho subversion repository, and import it into a new github repository, and then see if you can get Quercus to run without Resin. > As far as HipHop, from what I've seen it holds zero interest for me > right now.
