Let's take a look at an example: interface HasName { /** @return string / public function getName(); } class Name { public $name; } class User implements HasName { /* @return string\|Name */ public function getName() { return new Name('foo'); // This is a violation of the ``HasName`` interface // which only allows a string value to be returned. } } Loading history...
