GitHub Actions for Composer. Base on Docker official PHP image, and installed hirak/prestissimo package.

Actually, I want to follow DRY principle and use official Composer image. But see the following composer.json:

{
    "require": {
        "php": ">=5.5.9"
    },
    "require-dev": {
        "phpunit/phpunit": "^4 | ^5 | ^6"
    }
}

And use the following workflow:

- name: Composer install
  uses: docker://composer:1.9.1
  with:
    args: install
- name: PHPUnit testing
  uses: docker://php:5.5
  with:
    args: php vendor/bin/phpunit

It's expected to work on PHP 5.5 ~ 7.3, so we should test on every platform. However, Composer image will install on PHP 7.3 platform and it will install PHPUnit 6.x. It will failed on PHP 5.5 container for PHPUnit 6.x require PHP ^7.0.

Of course, we can use the config.platform.php config to force platform version on PHP 5.5 and it will install PHPUnit 4.x, but PHPUnit 4.x use too many deprecated functions, e.g. each(), so that cannot work on PHP >=7.2.

Finally, I think that build image on every version is the good idea.

Via GitHub Workflow

- uses: MilesChou/composer-action@master
  with:
    args: install

Use install image

- uses: MilesChou/composer-action/install@master

With specify PHP version

- uses: MilesChou/composer-action/5.5/install@master
