1.2.1323. Use DNF¶
This rule detects the usage of the DNF. DNF is the disjunctive Normal Form. It is a syntax to handle union and intersectional types at the same time. It was introducted in PHP 8.2.
DNF is available for every typed element of PHP : properties, arguments and returntype. It was extended to class constants on PHP 8.3.
<?php
class x {
const (A&B)|string C = 'string';
function foo((A&B)|(C&D) $e) {}
}
?>
