PHP Code Sniffer configuration

Please note that PHP Code Sniffer is in beta version and not enabled by default. If you'd like to try it out, please contact us at

PHPCS requires configuration via a phpcs.xml configuration file as detailed in PHP Code Sniffer's documentation.

If you don't specify your custom configuration file we use our default below. We suggest to add your own configuration file into your repository root directory to be able to specify your coding and quality standards.


<ruleset name="coding-style">

    <!-- 2.1. PHP Tags -->

Ignoring files

Storing generated or third party code in your repository is in general not a good idea. However, sometimes you really need to do this and Codeac got you covered. Usually you don't want to analyze those files so you can place .phpcsignore file to the root folder of your repository. This file can contain regular expressions that are matched with paths in your project and excluded from the analysis. The syntax is identical with popular gitignore format.

Take a look on this simple example with Composer and Protocol Buffers:


# 3rd party libraries
