我在这里http://blog.csdn.net/zdy4452406/article/details/8806962基于jquery+ajax实现的多选框，怎么读取数据库信息呢？PHP要怎么写？我的mysql数据表如下：
--
-- 表的结构 `3g_district`
--
CREATE TABLE IF NOT EXISTS `3g_district` (
`d_id` mediumint(8) unsigned NOT NULL AUTO_INCREMENT,
`d_name` char(255) NOT NULL,
`d_level` tinyint(4) unsigned NOT NULL DEFAULT '0',
`d_pid` mediumint(8) unsigned NOT NULL DEFAULT '0',
`d_list` smallint(6) NOT NULL DEFAULT '0',
PRIMARY KEY (`d_id`),
KEY `upid` (`d_pid`,`d_list`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=45052 ;
--
-- 转存表中的数据 `3g_district`
--
INSERT INTO `3g_district` (`d_id`, `d_name`, `d_level`, `d_pid`, `d_list`) VALUES
