Is it possible to somehow use some of the PHP classes that come with Zend in a Java project? I'd like to think that there's always a way, but how?

@Alfred, Haven't tried yet actually. Did you try it yourself?jblue– jblue2010-09-17 23:58:13 +00:00Commented Sep 17, 2010 at 23:58

For fun I created a simple little message queue in java which you could use. I did similiar stuff like this in the past on top redis. It works pretty good! I also did write a lot of simple webservices which could also work and is really easy to write! I guess you should start with writing a little simple webservice because that is really easy!Alfred– Alfred2010-09-18 00:16:13 +00:00Commented Sep 18, 2010 at 0:16

You could try using Quercus, a Java based PHP runtime. Other than that, you could write a web service in PHP, which is called by your Java code, or a command-line PHP script which is executed by Java.

yup I also Quercus is what I was also was thinking of as option.

+1 Thanks. but what is Quercus exactly? It sounds like a Java/PHP hybrid. Can it be added to Apache/PHP when the base is PHP or only when the base is Java. It's a bit of a strange concept for me.

+1 -- never heard of it before, will file away for reference.

@jblue Quercus caucho.com/resin-3.0/quercus is an implementation of PHP, but actually written in Java
Question you should ask yourself first
First some questions you should ask your self, which could help use give you the best answer(because programming is a lot of times about trade-offs):
Can you run PHP code natively: If it is not possible to run PHP code natively via (http/CLI) then your only option would be to try if Quercus does the job.
How much concurrency does PHP have: Let's assume you don't call PHP much. Then I would consider writing a simple webservice(see below)because this is the easiest to implement. If not a PHP deamon which is running in the background waiting for work(PHP) to process which it receives from java message queue(deamon), and sends the message to queue.
- How quickly should PHP respond to java: If quick then a daemon would be the way to go.
But I would first advice try to implement the easiest/quickest solution and benchmark it. The quickest solution could be written in a couple of minutes. The more difficult could take some time.
Solutions:
- Quercus: If you can't run PHP natively(CLI/HTTP) then this is your only option.
Simple webservice: let's say you call http://localhost:8181/zend/doZend.php?a=a&b=b from within your Java program. This would call:
doZendfunction with function parametersa&bfrom your corresponding PHP service- return results to Java program which called PHP service.
- A named pipe could also be quick/easy solution if you are in *nix. I assume this would out perform I think the queue part would perform better under high load, but this one is easier to implement.
- MessageQueue in java/C: write a PHP deamon which reads from a queue(redis blocking list pop(*nix)/write your own java version) and puts the answer on another blocking queue from which your Java program will read the answer when available. This option is a little bit hard to implement, but if scaling is a must I think this is the way to go. The redis part could(If not possible to compile it) also be replaced by a simple java deamon which only does have a blocking queue if desired. But the redis variant is really fast/stable and I would really go with that.
