Sonar PHPCS (PHP Codesniffer) plugin

This plugin can be used to import PHPCS reports into SonarQube.

The plugin will not run PHPCS but instead re-use the report generated by it. Here are the steps:

1. Download and install PHPCS on the machine or project running the SonarQube analysis
2. Get sonar-phpcs-plugin jar file:
   • Download from release
   • Or compile manually (Maven and at least JDK 17 is required):
     1. Clone project
     2. Run mvn verify
     3. Compiled jar file should be in target directory
3. Install this SonarQube PHPCS plugin (see instructions to manually install a SonarQube plugin)
4. Run PHPCS to create a json report e.g.:

phpcs --standard=PSR12 --report-json=output/phpcs.json src

3. Set the sonar.php.phpcs.reportPaths analysis property to the path of the PHPCS json report, e.g.:

sonar.php.phpcs.reportPaths=output/analysis/phpcs.json

4. Run the SonarQube analysis on your project
