"""
PHP Code Sniffer (PHPCS) Parser - PHP style and code standard enforcement.

PHP Code Sniffer is the industry-standard tool for detecting violations of
a defined set of coding standards in PHP code. It provides extensive
customization and integrates with numerous coding standards (PSR-1, PSR-2,
PSR-12, WordPress, Symfony, Zend, and custom standards).

PHPCS Features:
    - Style violation detection (spacing, naming, comments, etc.)
    - Code quality checks (complexity, duplication, unused code)
    - Customizable ruleset configuration
    - Automatic code fixing (phpcbf)
    - Multiple output formats (CSV, JSON, XML, etc.)
    - Custom sniff creation support
