The expression $instanceOf of type null|string is loosely compared to true; this is ambiguous if the string can be empty. You might want to explicitly use !== null instead.

Due to PHP Bug #53727, is_subclass_of might return inconsistent results on some PHP versions if $instanceOf can be an interface. If so, you could instead use ReflectionClass::implementsInterface.
