Our PHP Code Sniffer engine helps you detect violations of a defined coding standard.

It wraps the PHP_CodeSniffer static analysis tool. You can run it on your command line using the Code Climate CLI, or on our hosted analysis platform.

Enable the Plugin

To enable PHP Code Sniffer analysis, add the following to your .codeclimate.yml configuration file:

plugins:
  phpcodesniffer:
    enabled: true

More information about the CLI is available in the README here: https://github.com/codeclimate/codeclimate

Configure the Plugin

Extensions

You can specify which file extensions you'd like our PHP Code Sniffer engine to analyze by adding a file_extensions key nested under an engine config key in your .codeclimate.yml:

plugins:
  phpcodesniffer:
    enabled: true
    config:
      file_extensions: "php,inc,lib"

Standard

You can specify a list of standards that you want PHP Code Sniffer to use while analyzing your files by adding a standard key, nested under an engine config key in your .codeclimate.yml:

plugins:
  phpcodesniffer:
    enabled: true
    config:
    	standard: "PSR1,PSR2"

You can also indicate PHP CodeSniffer to use custom external rule set by specifying the relative path to the rules set's root directory on the command line.

plugins:
  phpcodesniffer:
    enabled: true
    config:
    	standard: "my_custom_php_ruleset.xml"
