This SonarSource project is a static code analyzer for PHP language used as an extension for the SonarQube platform. It will allow you to produce stable and easily supported Clean Code by helping you find and correct bugs, vulnerabilities, and code smells.

• 200+ rules
• Supports up to PHP 8.3
• Metrics (complexity, number of lines, etc.)
• Import of unit test and coverage results
• Support of custom rules

• Project homepage
• Documentation
• Issue tracking
• Available rules
• SonarSource Community Forum
• Demo project analysis

• Control Flow Graph documentation

To provide feedback (request a feature, report a bug, etc.) use the SonarSource Community Forum. Please do not forget to specify the language (PHP!), plugin version, and SonarQube version.

If you have a question on how to use plugin (and the docs don't help you), we also encourage you to use the community forum.

To request a new feature, please create a new thread in SonarSource Community Forum. Even if you plan to implement it yourself and submit it back to the community, please start a new thread first to be sure that we can follow up on it.

To submit a contribution, create a pull request for this repository. Please make sure that you follow our code style and that all tests are passing.

If you have an idea for a rule but you are not sure that everyone needs it you can implement a custom rule available only for you.

• 3.32 (October 2023)
  • Additional newIssue endpoint added to the CheckContext API interface
• 3.15 (January 2021)
  • PHPCustomRulesDefinition was removed, it was deprecated since version 2.13 (March 2018)
  • Removed dependency on sslr-squid-bridge which is not maintained anymore
• 3.11, support of PHP 8:
  • ParameterTree#type() is deprecated. Use ParameterTree#declaredType() instead.
  • ReturnTypeClauseTree#type() is deprecated. Use ReturnTypeClauseTree#declaredType() instead.
  • ClassPropertyDeclarationTree#typeAnnotation() is deprecated. Use ClassPropertyDeclarationTree#declaredType() instead.
  • CatchBlockTree#variable() can now return NULL.
  • FunctionCallTree#arguments() is deprecated. Use FunctionCallTree#callArguments() instead.
  • AnonymousClassTree#arguments() is deprecated. Use AnonymousClassTree#callArguments() instead.
  • New tree: CallArgumentTree. This tree wraps expressions passed as arguments now.
  • New kind of expression: ThrowExpressionTree.
  • New kind of expression: MatchExpressionTree.
  • ParameterTree now has a visibility method.

To run tests locally follow these instructions.

To build the plugin and run its unit tests, execute this command from the project's root directory (you will need Maven):

mvn clean install

To run integration tests, you will need to create a properties file like the one shown below, and set its location in an environment variable named ORCHESTRATOR_CONFIG_URL.

# version of SonarQube server
sonar.runtimeVersion=9.9

Before running any of the integration tests make sure the submodules are checked out:

  git submodule init
  git submodule update

The "Plugin Test" is an additional integration test that verifies plugin features such as metric calculation, coverage, etc. To launch it, execute this command from the directory its/plugin:

mvn clean install

The "Ruling Test" is a special integration test that launches the analysis of a large code base, saves the issues created by the plugin in report files, and then compares those results to the set of expected issues (stored as JSON files). To launch the ruling test:

cd its/ruling
mvn clean install

This test gives you the opportunity to examine the issues created by each rule and make sure they're what you expect. You can inspect new/lost issues by checking the web pages mentioned in the logs at the end of the analysis:

INFO  - HTML Issues Report generated: /path/to/project/sonar-php/its/sources/src/.sonar/issues-report/issues-report.html
INFO  - Light HTML Issues Report generated: /path/to/project/sonar-php/its/sources/src/.sonar/issues-report/issues-report-light.html

If everything looks good to you, you can copy the file with the actual issues located at

sonar-php/its/ruling/target/actual/

into the directory with the expected issues

sonar-php/its/ruling/src/test/resources/expected/
