As part of this lecture, I will be able to share the experience of writing production code for an enterprise application in PHP that works under the WAMP protocol. I'll tell you about the real experience of using such technologies as WAMP, Crossbar, Thruway, spawning of child processes, communication between the child and the host process. I'll tell you about the questions and difficulties that we faced, and, of course, about how we solved them. I can also add that we used this approach to the development of the application, launching sales for Eurovision 2017. The approach was tested in the most combat conditions.
