        }
    }
  foreach($p as $v)
        {
            $values[$v->getId()]['option_type_id']= $v->getId();
                $values[$v->getId()]['title']= 'test';
                $values[$v->getId()]['price']= 23;
                $values[$v->getId()]['price_type']= 'fixed';
                $values[$v->getId()]['sku']= $value1;
