PHP_CodeSniffer (PHPCS) is a tool for checking code quality in PHP. It can be used to ensure that your code follows a given coding standard, such as the WordPress Coding Standards. It can also be used to detect syntax errors and other issues in your code.

To use PHPCS in WordPress development, you will need to install it on your computer. This can typically be done using composer:

composer global require "squizlabs/php_codesniffer=*"

Once PHPCS is installed, you can use it to check the code quality of your WordPress plugin or theme by running the following command:

phpcs path/to/your/code

You can also use PHPCS with your text editor or IDE to get real-time feedback on your code as you write it.

In addition to checking for coding standards violations, PHPCS can also be used to automatically fix many coding standards issues using the phpcbf command.
