なぜこれを行うのですか:
$object->customer->phone =
! empty( $object->customer->address->phone_fixed ) ?
$object->customer->address->phone_fixed :
! empty( $object->customer->address->phone_mobile ) ?
$object->customer->address->phone_mobile :
! empty( $object->customer->address->phone_business ) ?
$object->customer->address->phone_business : '';
が設定されていて空でない$object->customer->address->phone_business
場合でも、を返しますか?$object->customer->address->phone_fixed
ありがとうございました。
