What are the essential tools for clean PHP development, such as linting and code formatting, similar to those used in JavaScript development?

When developing in PHP, it is essential to maintain clean and consistent code to improve readability and maintainability. Just like in JavaScript development, tools such as linters and code formatters can help achieve this. PHP_CodeSniffer is a popular linter that can check PHP code against coding standards, while PHP-CS-Fixer can automatically format PHP code based on predefined rules.

// Example of using PHP_CodeSniffer to check PHP code against coding standards
