PHP读取数据库显示问题
请教各位，我的数据库数据如下：-
— 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 I/本文来源gao@!dai!ma.com搞$$代^@码5网@搞代gaodaima码NTO `3g_district` (`d_id`, `d_name`, `d_level`, `d_pid`, `d_list`) VALUES
(1, ‘北京市’, 1, 0, 0),

(21, ‘海南省’, 1, 0, 0),
(22, ‘重庆市’, 1, 0, 0),
(23, ‘四川省’, 1, 0, 0),
我的conn.php文件如下：
<?php
$mysql_server_name=”localhost”; //数据库服务器名称
$mysql_username=”root”; //连接数据库用户名
$mysql_password=””; //连接数据库密码
$mysql_database=”teafea”; //数据库的名字
//连接到数据库
$conn=mysql_connect($mysql_server_name,$mysql_username,$mysql_password);
//使用utf8编码
mysql_query(“set names ‘utf8′”);
//从表中提取信息的sql语句
$str=”select d_id,d_name from 3g_district”;
//执行sql查询
mysql_select_db($mysql_database,$conn);
$res=mysql_query($str,$conn);
