解决办法就是: 读取的数据设置好编码方式； 发邮件的时候也指定编码方式；
先用函数base64_encode() 使用 MIME base64 对数据进行编码
标题字符串前加编码类型例如： =?UTF-8?B?
当然如果是gb2312的话就 =?GB2312?B?
标题字符串后加：?=

<html>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<body>
<?php
if(strlen($_POST["from"]) > 1)
//if "email" is filled out, send email
{
//send email
$email = $_POST["from"] ;
$mailto = $_POST["mailto"];
$subject = "=?UTF-8?B?" . base64_encode($_POST["subject"]) . "?=";
$message = $_POST["message"] ;
$header = 'MIME-Version: 1.0' . "\r\n"
. "Content-type: text/html; charset=utf-8". "\r\n"
. "From: <$email>"."\r\n";
//echo "mailto:$mailto<br />", "Subject: $subject<br />", "message:$message<br />", "From: $email<br />" ;
mail("$mailto", "$subject", $message, "$header" );
echo "<br />Your mail has been sent !
