这是源代码


{
include ( "inc_online.php" );
if ( !$CONF_MYSQL ) include( "conf_mysql.php" );
header( "Content-type: text/plain" );
header( "Content-Disposition: attachment; filename=成员地址.txt" );
echo sprintf( "%80s %80s %80s\r\n" , "作者" ,"内容" ,"时间");
$trans = array( " " => "　" , "<" => "<" , ">" => ">" , "&" => "&" );
$Myres = mysql_query( "select t1.*, t2.name from mc2_word as t1, mc2_member as t2 where t1.author=t2.username and t2.classname='{$_SESSION['mc2_class']}'order by t1.id" , $Mylink );
while ( $objWord = mysql_fetch_object( $Myres ) ) {
printf( "%80s %80s %80s\r\n" ,
$objWord->author ,
$objWord->content,
$objWord->time) ;
}
}


记事本内的内容完全正确
就是标题是乱码
这样显示 鎴愬憳鍦板潃.txt
是不是编码的事
应该怎么改
谢谢。
