README

A PHP starter to ease project creation

Details

Use this project as a starter for your PHP library!

Feaures

• Docker - Develop and test your plugin with Docker. Use an environment tailored for your plugin. See changes instantly in the browser. Build a Docker image containing a complete WordPress installation with your plugin and all pre-requisites.

• PHPStorm - Configuration for integrations of arguably the best PHP IDE out there, including:

  • Composer - Install and manage PHP dependencies on the correct version of PHP without leaving the IDE.
  • PHPUnit - Run tests and get reports directly in PHPStorm.
  • xDebug - Set breakpoints and inspect your code in PHPStorm.
  • Code coverage - See what has not been tested yet in a friendly GUI.

• Static Code Analysis - Maintain a consistent coding style, and catch problems early.

  • Psalm - Inspects your code for problems.
  • PHPCS - Checks your code style. PHPCBF can fix some of them automatically.

• Continuous Integration - Automatically verify that all contributions comply with project standards with GitHub Actions.

  • Composer vendor caching. Blazing-fast install.

Usage

Getting Started

Use Composer to bootstrap your project.

1. Clone and install deps:

   composer create-project dhii/php-project my_project

   Here, my_project is the name of the project folder.

2. Customize project

   Note: Asterisk * below denotes that changing this value requires rebuild of the images in order to have effect on the dev environment.

   • Copy .env.example to .env.

   • .env:

     • BASE_PATH - If you are using Docker Machine, i.e. on any non-Linux system, set this to the absolute path to the project folder inside the machine. If you are on Linux, you do not need to change this.
     • PROJECT_NAME - Slug of your project. Used mainly for naming containers with container_name. This is helpful to run multiple projects on the same machine.
     • PHP_BUILD_VERSION - The version of PHP, on which the plugin will be built. This should correspond to the minimal PHP requirement of your plugin. Used to determine the tag of the php image.
     • PHP_TEST_VERSION* - The version of PHP, on which the plugin will be run. This should correspond to the maximal PHP requirement of your plugin. Used to determine the tag of the php image.

   • composer.json:

     • name - Name of your package.
     • description - Description of your package.
     • authors - You and/or your company details.
     • require - Your project's package and platform requirements. You may want to change the PHP version if your minimal requirement is different. Don't forget to update PHP_BUILD_VERSION in .env.
     • require-dev - Your project's development requirements. Tools for testing and code quality.

Updating Dependencies

Composer is installed into the build service's image. To run composer commands, use docker-compose run. For example, to update dependencies you can run the following:

docker-compose run --rm build composer update

If you use PHPStorm, you can use the composer integration, as the project is already configured for this.

Testing Code

This bootstrap includes PHPUnit. It is already configured, and you can test that it's working by running the sample tests:

docker-compose run --rm test vendor/bin/phpunit

If you use PHPStorm, you can use its PHPUnit integration: right-click on any test or folder inside the tests directory, and choose "Run". This will do the same as the above command. Because the test service is used for tests, they will be run with its PHP version, which should correspond to your project's minimal requirements, but can be something else if you want to test on a system that has different specs.

Debugging

The bootstrap includes xDebug in the test service of the Docker environment, and PHPStorm configuration. To use it, right click on any test or folder within the tests directory, and choose "Debug". This will run the tests with xDebug enabled. If you receive the error about xdebug.remote_host being set incorrectly and suggesting to fix the error, fix it by setting that variable to your machine's IP address on the local network in the window that pops up. After this, breakpoints in any code reachable by PHPUnit tests, including the code of tests themselves, will cause execution to pause, allowing inspection of code.

Static Analysis

• Psalm

  Run Psalm in project root:

  docker-compose run --rm test vendor/bin/psalm

  • Will also be run automatically on CI.
  • PHPStorm integration config included.

• PHPCS

  Run PHPCS/PHPCBF in project root:

  docker-compose run --rm test vendor/bin/phpcs -s --report-source --runtime-set ignore_warnings_on_exit 1
  docker-compose run --rm test vendor/bin/phpcbf

  • By default, uses PSR-12 and some rules from the Slevomat Coding Standard.
  • Will also be run automatically on CI.
  • PHPStorm integration config included.
