PHP_CodeSniffer is a set of two PHP scripts; the main phpcs script that tokenizes PHP, JavaScript and CSS files to detect violations of a defined coding standard, and a second phpcbf script to automatically correct coding standard violations. PHP_CodeSniffer is an essential development tool that ensures your code remains clean and consistent.
The PHP Coding Standards Fixer (PHP CS Fixer) tool fixes your code to follow standards; whether you want to follow PHP coding standards as defined in the PSR-1, PSR-2, etc., or other community driven ones like the Symfony one. You can also define your (teams) style through configuration.
