README

Common PHP coding standards for use in our PHP projects.

Setup

In a PHP project, do the following to set up the coding standards check:

Require the package

composer require --dev sincos/php-coding-standards

Add an empty tests output folder

mkdir tests/_output
touch tests/_output/.gitkeep

PHPCS and PHPMD will dump their reports in this folder.

Ignore files in the new _output folder

Add tests/_output to your .gitignore file.

Add phpcs.xml

Here is an example file:

<?xml version="1.0"?>
<ruleset name="Project name here">
    <config name="installed_paths" value="../../sincos/php-coding-standards/phpcs" />

    <rule ref="Sincos"/>

    <arg name="extensions" value="php"/>
    <file>./src</file>

    <!-- Rule customization/configuration example -->
    <rule ref="SlevomatCodingStandard.Files.TypeNameMatchesFileName">
        <properties>
            <property name="rootNamespaces" type="array">
                <element key="src" value="Sincos\Bring"/>
                <element key="tests" value="Sincos\Bring\Tests"/>
            </property>
        </properties>
    </rule>
</ruleset>

Add phpmd.xml

<?xml version="1.0"?>
<ruleset name="Project name here"
         xmlns="http://pmd.sf.net/ruleset/1.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://pmd.sf.net/ruleset/1.0.0 http://pmd.sf.net/ruleset_xml_schema.xsd"
         xsi:noNamespaceSchemaLocation="http://pmd.sf.net/ruleset_xml_schema.xsd">
    <description>
        A nice description here
    </description>

    <exclude-pattern>vendor</exclude-pattern>

    <rule ref="vendor/sincos/php-coding-standards/phpmd/ruleset.xml"/>
</ruleset>

Add a Makefile

This is optional, but makes the commands easier to run with sensible defaults:

After adding this to Makefile, you can run for instance make lint:

.DEFAULT_GOAL := help
.PHONY: help

help:
	@awk 'BEGIN {FS = ":.*?## "} /^[a-zA-Z_-]+:.*?## / {printf "\033[36m%-30s\033[0m %s\n", $$1, $$2}' $(MAKEFILE_LIST) | sort

phpcs: ## Check PHP Code Sniffer rules. (Optional parameter PARAMS="-additional --params")
	vendor/bin/phpcs --standard=phpcs.xml -d date.timezone=Europe/Oslo --report=junit --report-file=tests/_output/phpcs.xml -d memory_limit=512M $(PARAMS) -s

phpmd: ## Check PHP Mess Detector rules.
	vendor/bin/phpmd . xml phpmd.xml --suffixes php --reportfile tests/_output/phpmd.xml -d memory_limit=512M

phpcbf: ## Run PHPCBF to fix code
	vendor/bin/phpcbf .

lint: ## Run phpcs and phpmd (Optional parameter "FIX=true" added phpcbf on start)
ifdef FIX
	-make phpcbf
endif
	make phpcs
	make phpmd

Add all this sauce to your CI

Here is an example from another project using Circle CI, where we add the following to .circleci/config.yml:

# PHP CircleCI 2.0 configuration file
#
# Check https://circleci.com/docs/2.0/language-php/ for more details
#
version: 2
jobs:
  build:
    docker:
      - image: circleci/php:7.2.8-node-browsers

    steps:
      - checkout
      - run: sudo composer self-update
      - run: composer install
      - run: ./vendor/bin/phpunit
      - run: make lint
      - store_test_results:
          path: tests/_output
      - store_artifacts:
          path: tests/_output
