Subject: [PATCH] Fix PHP8.1 sfForm - Unsupported operand types: array + null
 on sfForm::updateValues()

Avoid error:
Fatal error: Uncaught TypeError: Unsupported operand types: array + null in lib\form\sfForm.class.php:319

Step to reproduce :
$form = new sfForm();
$form->updateValues(array('foo' => 'value'));

PHP 5.3 coding style

May use sfForm::getValues(), but as sfForm::updateValues() is a hack, it could be used before bind ($this->isBound = true);
