Is there any framework to have Java and Php interoperability?

Question

I have a few modules of an application that have been written in Java. But now, I have been asked to write all the other modules in PHP.

Is there any tool that will permit me to make method calls from PHP to Java and vice versa?
If not, is it possible to develop one especially considering the fact that Java is a strongly typed language unlike PHP?

For the love of (deity) don't do that. That's really, really bad software design. — Matti Virkkunen, Feb 05 '12 at 16:36
How much Java is there? You might be better off just rewriting it and sticking with and avoiding the mix. — BillRobertson42, Feb 05 '12 at 16:39
Around 40% has already been done in Java. So I am a little confused about what I should be doing — Lavanya Mohan, Feb 05 '12 at 16:51
Write the rest of them in Java as well and ignore whoever asked you to write it in PHP — The Nail, Feb 05 '12 at 17:09

Without knowing more I would suggest that you expose the Java methods as a web service. This has a number of other benefits outside of just language independent consumption.

However, web services might not be the answer if your java modules are very granular.

You might find it easiest if you use one of the solutions that enables you to run PHP on the JVM. This should give you pretty good interoperability. e.g.

Having said that, if you're already using Java modules, I can't see a huge amount of value in adding PHP into the mix as well. Why not just stick with Java? Java is already pretty much the best all-round platform choice for server side applications once you consider things like library ecosystem, tools, portability, performance, maturity, maintainability etc.

You can use nice frameworks like Play (Java/Scala) or Grails (Groovy) or Noir (Clojure) if you want productive web development on top of the Java stack, I think I would choose these in preference to most of the PHP frameworks available.
