I think in this example the check for null can be removed.
The feature is so much more useful than presented here.
(https://www.php.net/releases/8.2/en.php#dnf_types)
class Foo {
public function bar((A&B)|null $entity) {
- if ($entity === null) {
- return null;
- }
return $entity;
}
}
Best regards

I'd also like to point out that this doesn't cause a fatal error, at
least in the latest RC (I haven't tried the official release yet).
trait Foo
{
public const CONSTANT = 1;
public function bar(): int
{
return self::CONSTANT; // Fatal error
}
}
class Bar
{
use Foo;
}
var_dump(Bar::CONSTANT); // 1
var_dump((new Bar)->bar()); // 1

I think accordingly there should only be a single if-statement in the
PHP < 8.2 code sample.
I'd also like to point out that this doesn't cause a fatal error, at
least in the latest RC (I haven't tried the official release yet).trait Foo
{
public const CONSTANT = 1;public function bar(): int { return self::CONSTANT; // Fatal error }}
class Bar
{
use Foo;
}var_dump(Bar::CONSTANT); // 1
var_dump((new Bar)->bar()); // 1
Indeed, this example is borked. There is no fatal error at this place
prior to PHP 8.2.0 either; rather, line 5 raises a fatal error ("Traits
cannot have constants").
