## What it is
PHP_CodeSniffer is a set of two PHP scripts: phpcs tokenizes PHP files to detect violations of a defined coding standard, and phpcbf automatically corrects those violations. It is the official continuation of the abandoned squizlabs package and supports standards like PSR1 and PSR12.

## Use cases
- enforce PSR-12 coding standards on a PHP codebase
- automatically fix coding standard violations in PHP files
- run code style checks in CI pipelines
- check PHP code style before committing
- customize a coding standard for a PHP team

## When to choose
- you need to enforce or auto-fix PHP coding standards
- you want a mature, widely adopted PHP linting tool with CI integration

## When to avoid
- you need full static analysis beyond style checking (use PHPStan or Psalm)
- you are linting languages other than PHP

## Facets
- artifact type: cli-tool
- maturity: active
- function: linter, formatter, static-site-generator, cli, developer-tools
- domain: developer-tools, testing
- platform: php, cli, cross-platform
- tags: coding-standards, phpcs, phpcbf, psr12, static-analysis, code-quality, qa, command-line, automation
