<?xml version="1.0"?> <ruleset name="Coding standard"> <description>Coding standard</description> <!-- display progress --> <arg value="p" /> <arg name="colors" /> <!-- inherit rules from: --> <rule ref="Shlinkio" /> <!-- [...] --> </ruleset>

]. - Make all class constants to have a visibility modifier (
public
,protected
orprivate
). - Require function arguments with a default
null
value to be defined as nullable (?string $foo = 'foo'
). - Require function arguments to have a native type hint whenever possible.
- Require functions to have a native return type hint whenever possible.
- Require properties to have a native type hint whenever possible.
- Require non-capturing catch when the exception variable is not used.
