This Github Action runs PHPCompatibility/PHPCompatibility on your source code in an easy way.

PHPCompatibility is a set of sniffs for PHP CodeSniffer that checks for PHP cross-version compatibility. It will allow you to analyse your code for compatibility with higher and lower versions of PHP. This way you can confidently make changes to your code and make sure you don't break backwards compatibility on it.

The v1 branch of the action uses the latest stable release of PHPCompatibility (^9.3), however this release does not have any checks for PHP 8.x, so using pantheon-systems/phpcompatibility-action@v1 with test-versions: 8.0- will not check anything.

If you need to run 8.x checks on your project, use the dev branch of the phpcompatibility-action, e.g.: uses: pantheon-systems/phpcompatibility-action@dev. The dev branch uses the develop branch of PHPCompatibility where some 8.x checks have been added.

Allows you to skip the usage of shivammathur/setup-php when running the action. Default: false.

Select the test versions to run PHPCompatibility. It supports any format accepted by PHPCompatibility (Default: 8.0-)

Paths to run compatibility check on. Default: ${{ github.workspace }}

uses: pantheon-systems/phpcompatibility-action@v1
with:
  test-versions: 7.4-
  paths: ${{ github.workspace }}/src

This project uses our autotag action. New releases are created on each merge to main. See the autotag readme for details.
