The Nexylan Coding Standard is a set of configurations for many CS tools.
Nexylan Coding Standard is based on PSR and Symfony standards plus some rules from Slevomat Coding Standard.
Install it globally with php-code-sniffer (RECOMMENDED):
composer global require nexylan/coding-standard
Or, as a dependency of your project:
composer require --dev nexylan/coding-standard
Then add the standard on your ruleset.xml
file:
<?xml version="1.0"?>
<ruleset name="My project standard">
<rule ref="Nexylan"/>
</ruleset>
This is the quickest way, but you can of course personalize or disable some rules.
