从MySQL读取中文数据,显示???(问号)乱码的解决方法:
$db = &ADONewConnection(’mysql’);
$db->PConnect($dbhost, $dbusr, $dbpwd, $dbname);
mysql_query(”SET NAMES ‘GBK’”);//加上这句就可以了
$sql=”select * from user where us_id=’admin’”;
$rs=&$db->Execute($sql);
if (!$rs) {
print $db->ErrorMsg();
}
else {
$chinese_name=$rs->fields["ChineseName"];
}
$rs->Close();
$db->Close();
echo “欢迎您!”.$chinese_name;
?>
上面是使用adodb的写法,,不管用什么方式,只要加上 mysql_query(”SET NAMES ‘GBK’”); 就不会显示???,就正常显示了。
