Fea add action router

[cdesiles]

Introduce a new agnostic way of linting php.
To test it out:

jobs:
  php-linter:
    name: PHP Syntax check
    runs-on: ubuntu-latest
    strategy:
      matrix:
        php_version: ["7.1", "7.2", "7.3", "7.4", "8.0", "8.1"]
    steps:
      - name: Checkout
        uses: actions/checkout@v2.0.0
      - name: PHP syntax checker ${{ matrix.php_version }}
        uses: "jokesterfr/github-action-php-lint@fea-add-action-router"
        with:
          php-version: ${{ matrix.php_version }}

What happens if a syntax error is found? will this message be displayed anyway?

[cdesiles]

I don't think so, run will fail.

[cdesiles]

But you're right we should try this case.

[cdesiles]

git ls-files | grep -E '.*\.(php)' | xargs -n1 php -l -n | (! grep -v "No syntax errors" )

seems to provide exactly what's needed
