Conway's Game of life PHP implementation

This application is an example of php implementation of well known game using some Symfony 5.x components and PHP 7.4.x features.

I am using dependency injection, immutable value objects and producing readable and unit testable code. The first version was written few years as a test and is still maintained in order to present my PHP skills.

How to use

First, generate a new world into a xml file in order to create initial state. Then run the data import that will draw the life on the screen and save the last frame into another xml file.

Generate your world

World generation is simple and is done by following console command:

php app/console.php generate:world targetFile.xml 10 10 15

The first argument is a file that will describe the world and its occupants. The other parameters are a number of organisms to life in the world, number of cells of which the world consists and number of life cycles.

Import and process the life

Then, you can start the life cycles:

php app/console.php import:xml sourceFile.xml targetFile.xml 2

The cycle reads initial state from sourceFile.xml and executes the logic. The last frame is saved into target file targetFile.xml in a format of source files so that they can be further processed as source files. The last argument is FPS for the writer.

Please, run the tests via composer ci and keep the code quality.

Enjoy.
