WPCS with Visual Studio Code

Installation

The easiest way to get started with PHP_CodeSniffer is to download the Phar files for each of the commands:
# Download using curl
curl -OL https://squizlabs.github.io/PHP_CodeSniffer/phpcs.phar
curl -OL https://squizlabs.github.io/PHP_CodeSniffer/phpcbf.phar

# Or download using wget
wget https://squizlabs.github.io/PHP_CodeSniffer/phpcs.phar
wget https://squizlabs.github.io/PHP_CodeSniffer/phpcbf.phar

# Then test the downloaded PHARs
php phpcs.phar -h
php phpcbf.phar -h

Composer

If you use Composer, you can install PHP_CodeSniffer system-wide with the following command:
composer global require "squizlabs/php_codesniffer=*"

Make sure you have the composer bin dir in your PATH. The default value is ~/.composer/vendor/bin/, but you can check the value that you need to use by running composer global config bin-dir --absolute.

Or alternatively, include a dependency for squizlabs/php_codesniffer in your composer.json file. For example:

{
    "require-dev": {
        "squizlabs/php_codesniffer": "3.*"
    }
}

You will then be able to run PHP_CodeSniffer from the vendor bin directory:
./vendor/bin/phpcs -h
./vendor/bin/phpcbf -h
