PHP Coding Standards Fixer

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 - @PER-CS, a wide community like the Symfony - @Symfony, or our opinionated one - @PhpCsFixer. 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 modernise your codebase towards newer PHP (e.g. @autoPHPMigration and @autoPHPMigration:risky) and newer PHPUnit (e.g. @autoPHPUnitMigration:risky).

There are also @auto and @auto:risky that aim to provide good base rules.

Supported PHP Versions

• PHP 7.4 - PHP 8.5

Note

Each new PHP version requires a huge effort to support the new syntax. That's why the latest PHP version might not be supported yet. If you need it, please consider supporting the project in any convenient way, for example, with code contributions or reviewing existing PRs. To run PHP CS Fixer on yet unsupported versions "at your own risk" - use --allow-unsupported-php-version=yes option.

Installation

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