Coding style¶

The XRL team closely follows the PSR-2 coding style.

Also, when developing, the following command can be used to check various aspects of the code quality:

$ vendor/bin/phing qa

It runs the following tools on XRL’s code to detect possible issues:

• PHP lint (php -l): checks PHP syntax
• PHP_CodeSniffer: checks code compliance with coding standard
• PDepend: identifies tight coupling between two pieces of code
• PHPMD (PHP Mess Detector): detects high-risk code structures
• PHPCPD (PHP Copy-Paste Detector): detects copy/paste abuse
• PHPUnit: checks unit tests
