Question

PHP: How to share data between threads on different servers?

Suppose server has opened separate threads for each connection.

I want to share the data without using database.

Lets say an example:

User1-->Logged in on server1-> Playing a game with x points(server is getting score by AJAX).
User2-->Logged in on server2-> Playing same game with y points(server is getting score by AJAX).

Now i want to make a list of all logged in user with current score(point) of game.
How can i do that without using database.

Answer 1

Use a shared memcached server and store the data there.

Memcache will act like you would do with a database but much faster, which might be the reason you don’t want to use a database here.
