PHP Dev Tools (for CodinGame or anywhere else)

Intro

CodinGame is a great coding site where you can practice and improve your coding skills in a fun way by solving puzzles or writing bots for multiplayer games.

At CG you don't really have to bother about setting up any local development environment: just start to write your code directly on the CG website using your browser, run there the provided test cases (for solo puzzles), and submit your solution when you feel ready.

Despite this, it brings some advantages if you make the effort and spend some time to set up a local dev environment with some additional tooling - especially if you already have lots of puzzle solutions and some longer or more complex code as well. The experience will also come in handy in other projects, outside the context of CodinGame. Most of the discussion in this playground is also applicable elsewhere.

Contents

This Tech.io playground explores several tools to make your life easier as a developer. Topics we will cover:

  • Running your code locally (php)
  • Using a code repository (git, GitHub)
  • Using an IDE (Visual Studio Code)
  • Finding bugs (Xdebug)
  • Checking and fixing the coding style (PHP CodeSniffer, PHP CS Fixer)
  • Static code analysis to catch bugs BEFORE you run the code (PHPStan)
  • Some great CodinGame-specific tools and websites by the community

We will also very briefly touch some tools that are not relevant when solving CodinGame puzzles, but it is still good to know about them for other projects:

  • Using a dependency manager (Composer)
  • Unit testing (PHPUnit, PEST)
  • Generating documentation (phpDocumentor)

Goals and non-goals

My goal with this playground is NOT to provide a full tutorial for each tool, I will really just highlight the basics (with an extra emphasis on why to use them), and also show how I personally use them with my CG activities. I will try to be beginner-friendly. (Professional php developers are surely using most of these tools already...) To limit article length, I still cannot cover all the details of the installation and usage. Links are provided if you need to go deeper.

I will also not discuss any puzzle, algorithm, or the PHP language itself here, the topic is solely the dev environment and tooling. While the specific discussion is for PHP, most topics (especially the Why? parts) are valid for other languages as well (even the specific toolset would be different).

Contributions welcome

If you have suggestions for improvements for this playground, please:

  • send me (TBali) a private message on CodinGame;
  • or give a pull request directly to the github repo of this playground;
  • or just leave a comment here on Tech.io.

Let's get started!
