Facebook Compiling PHP to Run on the JVM?

  • submit to reddit

An article popped up today claiming that Facebook is investigating compiling PHP to run on the JVM. Until now, Facebook has been using a PHP-to-C++ cross compiler. But the addition of invoke dynamic to Java seems to have opened up a new possibility for Facebook. 

Alexander Turner, the author of this article points out that using the Multi Language VM for PHP is somewhat analogous to what V8 has done for JavaScript: JIT compilation of interpreted languages shows a significant increase in speed. In fact, Alexander sees this as the beginning of the end for interpreters:

These are exciting times. Soon I expect interpretors and interpreted langauges to be confined to DSLs and all general-purpose coding to be running in a JIT environment or as up-front compilation. That will be good for companies, good for performance and good for the planet.

Either way, it's good to see another of the major companies taking the JVM seriously. It could certainly take a long time for Facebook to get to a stage where they can have their code running on a VM unless they leverage the Quercus or Project Zero implementations.

Unknown is whether this is actually happening, but it brings up an interesting debate. If you had a Facebook-size codebase written in PHP, would you take this approach? Node.js would certainly be a more fashionable alternative.
