Magento Extension Quality Program Coding Standard

Magento EQP Coding Standard is a set of rules and sniffs for PHP_CodeSniffer tool.

It allows automatically check your code against some of the common Magento and PHP coding issues, like:

• raw SQL queries;
• SQL queries inside a loop;
• direct class instantiation;
• unnecessary collection loading;
• excessive code complexity;
• use of dangerous functions;
• use of PHP superglobals;
• code style issues

and many others.

Magento Extension Quality Program Coding Standard consists of two rulesets - MEQP1 for Magento and MEQP2 for Magento 2. Each of them contains the rules depending on the requirements of each version.

Installation

Install all dependencies via Composer:

$ composer create-project --repository=https://repo.magento.com magento/marketplace-eqp magento-coding-standard

You’re required to authenticate; see Get your authentication keys for details.

Usage

$ cd magento-coding-standard

Select the standard to run with PHP_CodeSniffer. To check Magento extension run:

$ vendor/bin/phpcs /path/to/your/extension --standard=MEQP1

To check Magento 2 extension run:

$ vendor/bin/phpcs /path/to/your/extension --standard=MEQP2

By default, PHP_CodeSniffer will check any file it finds with a .inc, .php, .js or .css extension. To check design templates, you can specify --extensions=php,phtml option.

To check syntax with specific PHP version set paths to php binary dir:

$ vendor/bin/phpcs --config-set php7.0_path <dir-to-your-php7>
$ vendor/bin/phpcs --config-set php5.4_path <dir-to-your-php5.4>

Fixing Errors Automatically

PHP_CodeSniffer offers the PHP Code Beautifier and Fixer (phpcbf) tool. It can be used in place of phpcs to automatically generate and fix all fixable issues. We highly recommend run following command to fix as many sniff violations as possible:

$ vendor/bin/phpcbf /path/to/your/extension --standard=MEQP2

Dynamic Sniffs

Sniffs with complex logic, like MEQP2.Classes.CollectionDependency and MEQP2.SQL.CoreTablesModification require path to installed Magento 2 instance. You can specify it by running following command:

$ vendor/bin/phpcs --config-set m2-path <path-to-magento2>

Notice: Dynamic sniffs will not work without specified m2-path configuration option.

Notice: Don't forget to clear cache folder in project root directory if you are running sniffs for other Magento version

Marketplace Technical Review

To make sure, your extension will pass CodeSniffer checks on Level 1 of Magento Marketplace Technical Review, you could run phpcs command with --severity=10 option.

$ vendor/bin/phpcs /path/to/your/extension --standard=MEQP2 --severity=10

All severity 10 errors must be fixed in order to successfully pass Level 1 CodeSniffer checks.

Requirements

• PHP >=5.6.0
• Composer
• PHP_CodeSniffer 2.6.2

Notice: PHP and Composer should be accessible globally.
