[![SensioLabsInsight Medal](https://insight.sensiolabs.com/projects/a06c37c6-0d79-4476-aff5-12d8ce1d8c53/big.png "SensioLabsInsight Medal")](https://insight.sensiolabs.com/projects/a06c37c6-0d79-4476-aff5-12d8ce1d8c53)



ECG Magento Code Sniffer Coding Standard is a set of rules and sniffs for [PHP_CodeSniffer](https://github.com/squizlabs/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 instantiation of Mage and Enterprise classes;

- unnecessary collection loading;

- excessive code complexity;

- use of dangerous functions;

- use of PHP Superglobals;



and many others.



Both Magento and Magento 2 are supported.



# Installation



Before starting using our coding standard install [PHP_CodeSniffer](https://github.com/squizlabs/PHP_CodeSniffer).



The recommended installation method for PHPCS is globally with Composer:

```sh

composer global require "squizlabs/php_codesniffer=*"

```

Make sure Composer's bin directory (defaulted to `~/.composer/vendor/bin/`) is in your PATH.



Clone or download this repo somewhere on your computer or install it with [Composer](http://getcomposer.org/):



```sh

composer require magento-ecg/coding-standard

```



___



Note: PHP_CodeSniffer 3.x is now required to run our coding standard. To install PHP_CodeSniffer 2.x compatible version:



```sh

composer require magento-ecg/coding-standard:4.*

```



Add the ECG standards directory to PHP_CodeSniffer's installed paths:

```sh

$ ./vendor/bin/phpcs --config-set installed_paths /path/to/your/folder/vendor/magento-ecg/coding-standard

```



You can check Installation by running following command:



```

$ ./vendor/bin/phpcs -i

```

It should do the following output:

```

The installed coding standards are EcgM2, PEAR, Zend, PSR2, MySource, Squiz, PSR1, PSR12 and Magento2

```



# Usage CLI Tool 



Select a standard to run with CodeSniffer: EcgM2 for Magento 2



Run CodeSniffer:



```sh

$ ./vendor/bin/phpcs --standard=EcgM2,PSR2,Magento2 /path/to/code

```



This package is compatible with Composer Installer Plugins for PHPCS coding standards (such as https://github.com/Dealerdirect/phpcodesniffer-composer-installer) and can be automatically registered with PHPCS during installation.



To check design templates, you must specify `phtml` in the `--extensions` argument: `--extensions=php,phtml`



# Usage Hook pre-commit 



Get hook file from the existing repository.

```sh

$ /path/to/your/folder/vendor/magento-ecg/coding-standard/.githooks

```



Install Hooks on the project. Copy hook into the project GIT folder

```

cp -R ./vendor/magento-ecg/coding-standard/.githooks ./

```



To automate hooks installation for all developers, it needs to include the following lines into your project's composer.json

```

    "scripts": {

        "post-install-cmd": [

            "git config core.hooksPath .githooks"

        ],

        "post-update-cmd": [

            "git config core.hooksPath .githooks"

        ]

    }

```



Run composer install to refresh the project state.

```

composer install

```



You are done!

Now, each product commit will be validated for an alignment with Magento Coding Standards. 



# Usage PHPStorm



PhpStorm provides code style check through integration with the PHP Code Sniffer tool, 

which validates your code for consistency with a coding standard and best practices.



Once Tool installed and configured in PhpStorm, the tool is available in any opened PHP file. 

Errors and warnings reported by PHP Code Sniffer on-the-fly are displayed as popup messages.

Note: We would also suggest enabling PHP Mess Detector validation as well.

Note: in case of using a Docker or VM, It needs to configure new PHPCS CLI Interpreter which will point out to VM/Docker.
