The PHP Coding Standards Fixer (PHP CS Fixer) fixes your code to follow the standards.

If you are already using a linter to identify coding standards problems in your code, you know that fixing them by hand is tedious, especially on large projects. This tool not only detects them, but also fixes them for you.

PHP CS Fixer has built-in rule sets, whether you want to follow PHP coding standards as defined by PHP-FIG's PER Coding Style, a wide community like the Symfony, or our opinionated one. You can also define your (team's) style through the configuration file.

PHP CS Fixer can not only unify the style of your code, but also help to modernize your codebase towards newer PHP (e.g. @autoPHPMigration) and newer PHPUnit (e.g. @autoPHPUnitMigration:risky).

• PHP 7.4 - PHP 8.4

The recommended way to install PHP CS Fixer is to use Composer:

composer require --dev friendsofphp/php-cs-fixer
## or when facing conflicts in dependencies:
composer require --dev php-cs-fixer/shim

For more details and other installation methods (also with Docker or behind CI), see installation instructions.

Assuming you installed PHP CS Fixer as instructed above, you can run the following command to fix the PHP files in the src directory:

./vendor/bin/php-cs-fixer fix src

See usage, list of built-in rules, list of rule sets and configuration file documentation for more details.

If you need to apply code styles that are not supported by the tool, you can create custom rules.

Native support exists for:

• PhpStorm

Community plugins exist for:

• NetBeans
• Sublime Text
• Vim
• VS Code
