PHPCS is a command-line tool that checks the code against a set of predefined coding standards. It uses sniffs, which are rules or guidelines, to identify potential issues or violations in the code. PHPCS can be customized to adhere to a specific coding standard.

Integrating PHPCS into your WordPress development workflow offers several advantages. By enforcing coding standards, you can ensure consistent code quality across your projects, making the codebase easier to maintain and collaborate on. Additionally, PHPCS helps identify and fix potential bugs, security vulnerabilities, and performance issues by catching them during development.
4. Setting Up PHPCS in WordPress 4. Setting Up PHPCS in WordPress
To set up PHPCS in your WordPress development environment, follow these steps:
-
Install PHP_CodeSniffer globally by running the following command:
composer global require "squizlabs/php_codesniffer=*"
-
Install the WordPress coding standards by executing the command:
git clone -b master https://github.com/WordPress/WordPress-Coding-Standards.git ~/.composer/vendor/wp-coding-standards
-
Add the WordPress coding standards to PHPCS by running:
phpcs --config-set installed_paths ~/.composer/vendor/wp-coding-standards
-
Verify the installation by running:
phpcs -i
You should see “WordPress” in the output.
5. Creating a Custom Coding Standard 5. Creating a Custom Coding Standard
Sometimes, you may need to create a custom coding standard for your WordPress project. Here’s how you can do it:
- Create a new directory for your custom coding
standards, for example,
my-coding-standards`.
-
Inside the
my-coding-standards
directory, create aruleset.xml
file that defines your custom coding standards. You can start by copying and modifying the default WordPress coding standardsruleset.xml
file. -
Customize the ruleset.xml file to fit your project’s coding standards. You can enable or disable specific rules or add new rules to meet the requirements of your project.
-
Once you have defined your custom coding standards, add them to your PHPCS configuration by running the following command:
phpcs --config-set installed_paths ~/.composer/vendor/wp-coding-standards,~/path/to/my-coding-standards
Replace
~/path/to/my-coding-standards
with the actual path to yourmy-coding-standards
directory. -
Verify that your custom coding standards have been added by running:
phpcs -i
You should now see both the “WordPress” and your custom coding standards listed in the output.
-
You can now use your custom coding standards in your WordPress development workflow by running PHPCS with the
--standard
flag followed by your custom coding standards:phpcs --standard=my-coding-standards /path/to/your/php/files
This will validate your code against your custom coding standards and provide you with any coding guideline violations or potential issues.
-
Remember to regularly update your PHPCS and WordPress coding standards to benefit from the latest improvements and bug fixes.

Now that you have PHPCS set up with the WordPress coding standards and your custom coding standards, you can include it in your development workflow. Here are a few ways to make the most of PHPCS:
-
Use PHPCS as part of your code review process. Run PHPCS locally before committing your code to catch any coding violations or issues.
-
Integrate PHPCS into your continuous integration (CI) or build system, such as Jenkins or Travis CI. This ensures that all code written for your project complies with the defined coding standards.
-
Automate PHPCS checks in your code editor or IDE using plugins or extensions. This provides real-time feedback on coding violations as you write code, promoting adherence to the coding standards.
- Leverage PHPCS fixers to automatically fix coding violations identified by PHPCS. These fixers can automatically correct common issues, such as indentation, whitespace, and formatting.
7. Summary 7. Summary
Integrating PHPCS into your WordPress development workflow can greatly improve the quality and maintainability of your codebase. By enforcing coding standards, you ensure consistency and readability, making collaboration easier. PHPCS helps catch potential bugs, security vulnerabilities, and performance issues early in the development process. With the flexibility to create custom coding standards and the ability to automate checks, PHPCS becomes an indispensable tool in your development toolkit.
Remember to regularly update your PHPCS and WordPress coding standards to stay up-to-date with the latest improvements and best practices.
In conclusion, by incorporating PHPCS into your WordPress development workflow, you can write cleaner, more reliable code, ensuring a high level of quality and adherence to coding standards. Happy coding!
