php教程中文乱码问题和mysql教程出现中文乱码的解决方法
$mysql_server_name='localhost';
$mysql_username='root';
$mysql_password='000000';
$mysql_database='lib';
$conn=mysql_connect($mysql_server_name,$mysql_username,$mysql_password,$mysql_database);
$sql="select name,age from mytb";
print($conn);
$rs=mysql_db_query("lib","select * from mytb",$conn);
print("
");
while($row = mysql_fetch_object($rs)){
print ($row->name.":".$row->age."
");
}
mysql_close($conn);
?>
显示如下:
resource id #1
dd:54
ddd:8
??:15
???:25
??:32
mysql编码:utf8,gbk都试过了。mysql font 和命令行显示都正确。
问题补充:
乱码:
???:15
???:25
??:32
这几行,数据库教程里的值是汉字.显示出来的是问号.
解决办法:
在$rs=mysql_db_query("lib","select * from mytb",$conn);
前面加上
mysql_query("set names gb2312");或者mysql_query("set names gbk");
下面看一下关于解决乱码的方法
.gb2312,gbk,utf8等支持多字节编码的字符集都可以储存汉字,gb2312中的汉字数量远少于gbk,而gb2312,gbk等都可在utf8下编码。
二.用命令show variables like 'character_set_%';查看当前字符集设定:
mysql> show variables like 'character_set_%';
+--------------------------+--------+
| variable_name | value |
+--------------------------+--------+
| character_set_client | gb2312 |
| character_set_connection | gb2312 |
| character_set_database | gb2312 |
| character_set_filesystem | binary |
| character_set_results | gb2312 |
| character_set_server | latin1 |
| character_set_system | utf8 |
+--------------------------+--------+
7 rows in set (0.02 sec)
(这里设置的字符是gb2312)
显示中文乱码主要有两个设置:character_set_connection 和character_set_results ,
如果你的这两个设置不支持中文编码,就会出现乱码,只要:set character_set_results =gbk;就设置中文编码了。
三.set names charset_name;可以一次性设置客户端的所有字符集。
