## What it is
PHP CS Fixer is a command-line tool that detects and automatically fixes PHP coding standards issues. It ships with built-in rule sets (PER-CS, Symfony, PhpCsFixer, auto-migration sets) and supports custom team configurations.

## Use cases
- automatically fix php coding standards issues
- enforce per-cs or symfony coding style in a php project
- check code style in ci pipeline
- modernize php codebase to newer php syntax
- format php code consistently across a team
- replace manual lint fixing on large php projects

## When to choose
- you maintain a PHP project and want automated, opinionated code style fixing
- you need CI integration for style checks (GitHub Actions, GitLab CI, Docker)
- you want to migrate code style toward newer PHP or PHPUnit conventions

## When to avoid
- your project is not written in PHP
- you only need style detection without fixing and prefer a lightweight linter
- you need formatting for other languages - use language-specific formatters instead

## Facets
- artifact type: cli-tool
- maturity: stable
- function: formatter, linter, developer-tools, ci-cd
- domain: developer-tools, programming-languages
- platform: php, cli, cross-platform
- tags: php, code-style, coding-standards, static-analysis, auto-fix, per-cs, symfony, composer, automation, docker
