The expression $records of type array is implicitly converted to a boolean; are you sure this is intended? If so, consider using ! empty($expr) instead to make it clear that you intend to check for an array without elements.

new DateTimeImmutable() of type DateTimeImmutable is incompatible with the type integer expected by parameter $date of Swift_Mime_SimpleMessage::setDate().
