PHP Mess Detector (PHPMD) is a static analysis tool for PHP that helps detect potential problems in your code. It identifies a wide range of code issues, including:
PHPMD is configurable, allowing you to define custom rules or use predefined rule sets like "unused code" or "naming conventions." It works similarly to PHP_CodeSniffer, but while CodeSniffer focuses more on style and formatting issues, PHPMD is more focused on the logic and structure of the code.
In summary, PHPMD helps ensure code quality and maintainability by pointing out potential "messes" that might otherwise go unnoticed.
PHP_CodeSniffer, often referred to as "Codesniffer," is a tool used to detect violations of coding standards in PHP code. It ensures that code adheres to specified standards, which improves readability, consistency, and maintainability across projects.
In summary, PHP_CodeSniffer helps improve the overall quality and consistency of PHP projects, making them easier to maintain in the long term.
