CakePHP Code Sniffer

Build Status Total Downloads Latest Stable Version Software License

This code works with squizlabs/php_codesniffer and checks code against the coding standards used in CakePHP.

This sniffer package follows PSR-12 completely and ships with a lot of additional fixers on top.

List of included sniffs

Which version should I use?

See version map.


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. Alternatively, install the dealerdirect/phpcodesniffer-composer-installer composer package which will handle configuring the phpcs installed_paths for you.


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

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 --colors -p -s --standard=CakePHP /path/to/code/

You can also copy the phpcs.xml.dist file to your project's root folder as phpcs.xml. This file will import the CakePHP Coding Standard. From there you can edit it to include/exclude as needed. With this file in place, you can run:

vendor/bin/phpcs --colors -p -s /path/to/code/

If you are using Composer to manage your CakePHP project, you can also add the below to your composer.json file:

    "scripts": {
        "cs-check": "vendor/bin/phpcs --colors -p -s --extensions=php src/ tests/"

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.
