How to connect php and java?

Question

PHP

Hello! I have a site in php. Now you need to write an application in java and link them.
The scenario is simple: the java application will always be running, php sends requests to it and waits for a response. Java starts a thread, processes, returns. Data exchange in json.
In principle, we already have a queue server (gearman) - you can use it. There is redis - it is possible through its pub/sub.
But does anyone know a better way?
Thanks in advance.

Answer 1

pub/sub to rabbitmq/zeromq/activemq etc. Of course, you can organize RPC, but ...

Answer 2

Queues in my opinion - the most correct way.

Answer 3

Have you looked at Apache Thrift?
