The coding standard ruleset for strong code style checking.

This specification extends and expands PSR-12, the extended coding style guide and requires adherence to PSR-1, the basic coding standard. All additional checks and sniffs use from another third-party libraries:

  • slevomat/coding-standard
  • webimpress/coding-standard


  1. Install the module via composer by running:

    composer require --dev opsway/psr12-strict-coding-standard
  2. Add composer scripts into your composer.json:

    "scripts": {
      "cs-check": "phpcs",
      "cs-fix": "phpcbf"
  3. Run the init_phpcs.sh to generate the PHP_CodeSniffer ruleset into your project root:

    wget https://raw.githubusercontent.com/opsway/psr12-strict-modern-standart/master/init_phpcs.sh
    chmod +x ./init_phpcs.sh

    or, create a ruleset phpcs.xml in the project root with the following content (notice entries under <!-- Paths to check -->):

    <?xml version="1.0"?>
    <ruleset xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        <arg name="basepath" value="."/>
        <arg name="cache" value=".phpcs-cache"/>
        <arg name="colors"/>
        <arg name="extensions" value="php"/>
        <arg name="parallel" value="10"/>
        <!-- Show progress -->
        <arg value="p"/>
        <!-- Paths to check -->
        <!-- Include all rules from the Zend Coding Standard -->
        <rule ref="OpsWayStrictPSR12CodingStandard"/>

You can include or exclude relevant directories within file elements under <!-- Paths to check --> in the PHP_CodeSniffer ruleset above. For further reference, please see the PHP_CodeSniffer wiki: https://github.com/squizlabs/PHP_CodeSniffer/wiki/Annotated-ruleset.xml


  • To run checks only:

    $ composer cs-check
  • To automatically fix many CS issues:

    $ composer cs-fix


Rules can be added, excluded or tweaked locally, depending on your preferences. More information on how to do this can be found here:
