Have you ever had a project written primarily in PHP, but there were some java systems that you wanted to connect to? Perhaps there was a third party library or a java API that you really want (or are required) to use, but PHP had been chosen for other reasons.

The php java bridge is your solution. The documentation is good, and the performance is pretty darn good (if you’re looking for benchmarks, search for ‘How fast is it?’). You can use the bridge over sockets, a xml based protocol via servlets, or over a mono application. The mailing list is active, and it looks like the primary developer actually answers questions on said list (as of May 2007).

I’ve always been a bit hesitant regarding cross language programming: “Great, now I get to debug in two languages that communicate via sockets! Yahoo!”. But for a certain set of circumstances, using this bridge can be the right answer.
