The best way to deactivate an individual issue you don't intend to fix is to mark it Won't Fix or False Positive through the Sonar UI.
If you need to deactivate a rule (or all rules) for an entire file, then issue exclusions are the way to go. But if you only want to deactivate a rule across a subset of a file - all the lines of a method or a class - you can use a PHPDoc comment
/* @SuppressWarnings("php:S2077") */ or an attribute
The PHP analyzer can analyze
php.ini files with some specific rules (if these rules are activated in your quality profile).
php.ini files must be part of the project you are analyzing, meaning the
php.ini files have to be inside the directories listed in
sonar.sources. Rules targeting
php.ini files can be quickly identified through the "php-ini" tag set on them.
