Create a game in PHP (client + server + client)

You need a simple PHP game (client + server + client) where each user can play with another user. The game interface has already been thought out and designed, you only need to program the game itself so that it receives data from customers, processes, stores them in the database and gives the processed data to customers. The game itself in its likeness resembles the game "Balda", but there are its own characteristics. The dictionaries for the game are already prepared. There will be no automatic games, only between users.
