This code works with phpcs and checks code against the coding standards used in CakePHP.

⚠️ The master branch contains codesniffer rules that are based on the PSR2 standard. If you want to check against the historical CakePHP coding standard use any of the 1.x releases.

Which version should I use?

Sniffer version CakePHP version PHP min
1.x 2.x PHP 5.4
2.x 3.x PHP 5.5
3.x 3.x PHP 5.6
4.x 4.x PHP 7.1


You should install this codesniffer with composer:

composer require --dev "cakephp/cakephp-codesniffer"
vendor/bin/phpcs --config-set installed_paths /path/to/your/app/vendor/cakephp/cakephp-codesniffer

The second command lets phpcs know where to find your new sniffs. Ensure that you do not overwrite any existing installed_paths value.


Depending on how you installed the code sniffer changes how you run it. If you have installed phpcs, and this package with PEAR, you can do the following:

vendor/bin/phpcs --standard=CakePHP /path/to/code

⚠️ Warning when these sniffs are installed with composer, ensure that you have configured the CodeSniffer installed_paths setting.

Running Tests

You can run tests with composer. Because of how PHPCS test suites work, there is additional configuration state in phpcs that is required.

composer test

Once this has been done once, you can use phpunit --filter CakePHP to run the tests for the rules in this repository.


If you'd like to contribute to the Code Sniffer, you can fork the project add features and send pull requests.
