Still generically solvable in userland with creativity. :) trait ObjectFromArray { public static function fromArray(array $array, ...$params) { $object = new static(...$params); foreach ($array as $k => $v) { if (property_exists($object, $k)) { $object->{$k} = $v; } else { trigger_error('fubar', E_USER_ERROR); } } return $object; } } class SomeObject { use ObjectFromArray; private $foo; } SomeObject::fromArray(['foo' => 'bar', 'bar' => 'foo']); -- Richard "Fleshgrinder" Fussenegger
