A nice list of linting utility for PHP on the GitHub.
Inspired by the awesome list thing.

- PHP Mess Detector - PHPMD is a spin-off project of PHP Depend and aims to be a PHP equivalent of the well known Java tool PMD. PHPMD can be seen as an user friendly frontend application for the raw metrics stream measured by PHP Depend.
- PHP_CodeSniffer - PHP_CodeSniffer tokenizes PHP, JavaScript and CSS files and detects violations of a defined set of coding standards.
- PHP Parallel Lint - This tool check syntax of PHP files faster than serial check with fancier output.
