Drupal Coding Standards: Installing and Using CodeSniffer for Precise Code Checks in Ubuntu(phpcs and phpcbf)

Installation Code:

# Install Composer globally
curl -sS https://getcomposer.org/installer | php
sudo mv composer.phar /usr/local/bin/composer

# Install PHP CodeSniffer and Fixer globally
composer global require "squizlabs/php_codesniffer=*"
composer global require "drupal/coder"

# Add Composer global bin directory to the system PATH
echo 'export PATH="$PATH:$HOME/.composer/vendor/bin"' >> ~/.bashrc
source ~/.bashrc

Implementation for Drupal:

# Run PHP CodeSniffer for Drupal coding standards
phpcs --standard=Drupal,DrupalPractice --extensions=php,module,inc,install,test,profile,theme,css,js,info,txt,md,yml,twig module_folder/

# Run PHP CodeFixer to automatically fix some coding standard violations
phpcbf --standard=Drupal,DrupalPractice --extensions=php,module,inc,install,test,profile,theme,css,js,info,txt,md,yml,twig module_folder/

Ensure your Drupal module adheres to the Drupal coding standards effortlessly with these commands.
