Coding Guidelines

Make sure your IDE is setup properly to comply with the Coding Guidelines for TYPO3 (CGL).


Please note that there is an .editorconfig file in the TYPO3 core repository. See for more information. Use the EditorConfig plugin for PhpStorm.

If you use the .editorconfig file (which is included in the TYPO3 core), some standard formatting rules are already setup automatically (e.g. indent with 4 spaces for PHP files).

The rules defined in .editorconfig are very minimal and it is suggested to see the TYPO3 Coding Guidelines for more information and toolchain configuration. Please read PhpStorm documentation on using PHP CS Fixer for information on how to use the provided config.php within PhpStorm.

For a quick start, you can use the following PhpStorm code style to comply with PSR-12, which is the most recent recommendation at the time of this writing that PhpStorm provides a preset for:

PHP files

Set Predefined Style in PhpStorm: File > Settings > Editor > Code Style > PHP > Set From > Predefined Style

Choose PSR-12.

In order to test this, use Code: Reformat Code to reformat a PHP file.

You can find more information on the Coding Guidelines section in the Appendix.

Setting up PhpStorm for the Testing Framework


First setup the Testing Framework. Replace <YOUR_WEBROOT> with your path to the web directory. You must use absolute paths for this.

Setup Test Frameworks in PhpStorm: File > Settings > Languages & Frameworks > PHP: Test Frameworks:

(ctrl + alt + s opens File > Settings)

  • Use composer autoloader
  • Path to script: <YOUR_WEBROOT>/vendor/autoload.php
  • Test runner: Defaut configuration file: <YOUR_WEBROOT>/Build/phpunit/UnitTests.xml
  • Test Runner: Default bootstrap file: <YOUR_WEBROOT>/Build/phpunit/UnitTestsBootstrap.php
Setup Testing Framework

If this is setup correctly, it will be possible to run your unit tests from within the IDE.
