Contributions are welcome and will be fully credited.

We accept contributions via Pull Requests on Github.

The current stable major version is v5. The v6 is under active development.

This means any new feature MUST target v6 (master branch).

The v5 (5.x branch) is maintained only for bug fixes, node/edge updates or documentation improvements.

Code of Conduct

The code of conduct is described in

Pull Requests

  • Sign the CLA - For us to accept contributions you will have to first have signed the Contributor License Agreement.

  • PSR-2 Coding Standard - The easiest way to apply the conventions is to run PHP Code Sniffer as you code.

  • Add tests! - Your patch won't be accepted if it doesn't have tests.

  • Document any change in behaviour - Make sure the README and the documentation are kept up-to-date.

  • Consider our release cycle - As of version 5.0.0, we try to follow SemVer. Randomly breaking public APIs is not an option.

  • Create topic branches - Don't ask us to pull from your master branch.

  • One pull request per feature - If you want to do more than one thing, send multiple pull requests.

  • Send coherent history - Make sure each individual commit in your pull request is meaningful. If you had to make multiple intermediate commits while developing, please squash them before submitting.

  • Ensure tests pass! - Please run the tests before submitting your pull request, and make sure they pass. We won't accept a patch until all tests pass.

  • Ensure no coding standards violations - Please run PHP Code Sniffer using the PSR-2 standard before submitting your pull request. A violation will cause the build to fail, so please make sure there are no violations. We can't accept a patch if the build fails.

Running Tests

$ ./vendor/bin/phpunit

Running PHP Code Sniffer

You can install PHP Code Sniffer globally with composer.

$ composer global require squizlabs/php_codesniffer

Then you can cd into the Facebook PHP SDK folder and run Code Sniffer against the src/ directory.

$ ~/.composer/vendor/bin/phpcs

Happy coding!
