Coding Standards

The shopware team uses the following coding standards. All contributions to Shopware as well as plugins and customizations should also use these standards.


If not stated otherwise we use the following coding styles for all source files:

  • Unix-like newlines (Line Feed/LF, \n)
  • 4 spaces for indenting, not tabs
  • UTF-8 File encoding

PHP Coding Standard

For PHP Code all contributions should use the PSR-1: Basic Coding Standard and PSR-2: Coding Style Guide.

You can automatically check and fix the coding style with php-cs-fixer:

php-cs-fixer fix -v --level=psr2 /path/to/files
