README

Using CIG PHP coding standards ruleset for PHPCodeSniffer, you can analyse the codebase of your project for PHP compatibility with other _itcig projects.

What's in this repo ?

A ruleset for PHPCodeSniffer to check for PHP compatibility and standards across all _itcig PHP projects.

This WordPress specific ruleset prevents false positives from the PHPCompatibility standard by excluding back-fills and poly-fills which are provided by WordPress.

Requirements

These will all be installed automatically by this ruleset so you do not need to include them explicitly.

• PHP_CodeSniffer. Use the latest stable release of PHP_CodeSniffer for the best results. The minimum recommended version of PHP_CodeSniffer is version 3.0.2.
• PHPCompatibility 9.0.0+.

Installation instructions

The only supported installation method is via Composer.

If you already have a Composer PHP_CodeSniffer plugin installed, run:

composer require --dev itcig/php-coding-standards:"*"
composer install

Next, run:

vendor/bin/phpcs -i

If all went well, you will now see that the CIG, CIG-Docs, CIG-Wordpress, CIG-Core, PHPCompatibility, PHPCompatibilityWP and some more PHPCompatibility standards are installed for PHP_CodeSniffer.

How to use

Now you can use the following command to inspect your code:

./vendor/bin/phpcs -p . --standard=CIG

By default, you will only receive notifications about formatting and deprecated and/or removed PHP features.

To get the most out of the CIG coding and PHPCompatibility standards, you should specify a testVersion to check against. That will enable the checks for both deprecated/removed PHP features as well as the detection of code using new PHP features.

If you want to enforce the minimum PHP requirement, either add --runtime-set testVersion 7.2- to your command-line command or add <config name="testVersion" value="7.2-"/> to your custom ruleset.

For example:

# For a project which should be compatible with PHP 7.2 and higher:
./vendor/bin/phpcs -p . --standard=CIG --runtime-set testVersion 7.2-

For more detailed information about setting the testVersion, see the README of the generic PHPCompatibility standard.

Testing PHP files only

By default PHP_CodeSniffer will analyse PHP, JavaScript and CSS files. As the PHPCompatibility sniffs only target PHP code, you can make the run slightly faster by telling PHP_CodeSniffer to only check PHP files, like so:

./vendor/bin/phpcs -p . --standard=CIG --extensions=php --runtime-set testVersion 7.2-
