有这样的一个数组结构：

array (size=3)
  19 => 
    array (size=4)
      'pro_id' => string '44' (length=2)
      'attr_id' => int 19
      'attr_value' => 
        array (size=1)
          0 => string '12个月' (length=8)
      'attr_price' => 
        array (size=1)
          0 => string '200' (length=3)
  20 => 
    array (size=4)
      'pro_id' => string '44' (length=2)
      'attr_id' => int 20
      'attr_value' => 
        array (size=1)
          0 => string '按照5%计算' (length=14)
      'attr_price' => null
  18 => 
    array (size=4)
      'pro_id' => string '44' (length=2)
      'attr_id' => int 18
      'attr_value' => 
        array (size=2)
          0 => string '无发票0申报' (length=16)
          1 => string '按发票额申报' (length=18)
      'attr_price' => 
        array (size=2)
          0 => string '100' (length=3)
          1 => string '200' (length=3)
          

数据表结构如下：

我想要的结果如上，求怎么处理呀？？ 数据表结构

DROP TABLE IF EXISTS `dhd_product_attr`;
CREATE TABLE `dhd_product_attr` (
  `pro_attr_id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `pro_id` mediumint(8) unsigned NOT NULL DEFAULT '0',
  `attr_id` smallint(5) unsigned NOT NULL DEFAULT '0',
  `attr_value` text NOT NULL,
  `attr_price` varchar(255) NOT NULL COMMENT '该属性对应在产品原价格上要加的价格',
  PRIMARY KEY (`pro_attr_id`),
  KEY `pro_id` (`pro_id`),
  KEY `attr_id` (`attr_id`)
) ENGINE=MyISAM AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;

该怎么处理这个数组呀？？
