Download the PHP package atsmacode/poker-game without Composer

About

A database driven package that provides logic to drive a basic Texas Hold-Em poker game.

It can be pulled in via composer to be used within a parent front-end package, but could also be used within an independent container as an API.

A brief description of how it works is:

• The SitController starts a new Hand
• The PlayerActionController accept a Request containing information on which Hand is being played, and what the last thing to happen was (who was the last to act and what action did they take)
• This data is passed to the ActionHandler which updates the status of all players accordingly and returns a GameState object containing all the information of the current Hand
• The GameState is passed to a GamePlay class which decides what should happen next in the Hand
• Depending on what the next step is, the logic is delegated to respective HandStep interfaces which carry out the appropriate process for each thing:
  • The players are still betting on a street
  • A new street card should be dealt
  • All bets have been called on the river and we have reached showdown
  • A new Hand should be started
• If we have reached showdown, the Showdown class decides the winner by calling the HandIdentifier which identifies and ranks each hand the players have based on the ranking of active cards (a King would be the active card in a pair of Kings hand, for example) and kickers
• The updated GameState is returned

It is by no means a finished poker game. Here are some of the things it does not yet do:

• Split and side pots
• All-ins
• No-limit betting
• Game winners/losers as opposed to Hand winners/losers
• Incrementing blinds and antes

The testing is primarily based on Feature tests where I've set-up a range of scenarios.
