Generic.PHP.LowerCaseConstant and Generic.NamingConventions.UpperCaseConstantName are in conflict?

[tonebender]

Describe the bug

The Squiz ruleset has included BOTH Generic.NamingConventions.UpperCaseConstantName and Generic.PHP.LowerCaseConstant, which contradict each other. The former stipulates that true, false and null constants must always be uppercase, while the latter says that they must always be lowercase.

Which one should be followed, and why are both in the Squiz ruleset?

Code sample

From Squiz/ruleset.xml:

    <rule ref="Generic.NamingConventions.UpperCaseConstantName"/>
    <rule ref="Generic.PHP.LowerCaseConstant"/>

Versions (please complete the following information)

Operating System	Debian Linux
PHP version	8.2.24
PHP_CodeSniffer version	3.11.3
Standard	Squiz
Install type	Composer (local)

@tonebender Closing as invalid. Generic.NamingConventions.UpperCaseConstantName is about the declaration case for user-defined constants. There is no conflict between these rules.
