How to organize data exchange between C# and PHP?

Question

PHP

Hello.
There is a game server, authorization, highscore table, enemy search, written in PHP (Laravel).
The pvp combat itself is in C# (.net/win/mono) on the SuperSocket framework.
Are there ways to directly exchange messages and data between processes? While in the direction of PHP -> C#.
Now communication takes place through the database and the game client.
I already tried sockets and RabbitMQ, I'm looking for more options. Maybe there is something for UnixSignals Linux processes?

Answer 1

Shared memory is probably the fastest, but I'm not sure how easy it will be to cross PHP and C #, at least ready-made solutions are not known to me. Sockets and pipes are good for 99% of tasks, and they are about equally fast.
Perhaps it will be convenient for you to raise the REST interface in C #.
