PHP send UTF-8 code Chinese mail title garbled solution

When we use the following PHP statement to send Chinese e-mail, we will find that the title of the message is garbled, and the message body is correct, how to make the message title is not garbled?

$subject = stripslashes ($the _post[' Title '));
$headers = "Mime-version:1.0rn";
$headers. = "Content-type:text/plain; Charset=utf-8rn ";
$headers. = "CONTENT-TRANSFER-ENCODING:8BITRN";
$message = Stripslashes (strip_tags ($the _post[' Content '));
Mail ($to, $subject, $message, $headers);

First Use function Base64_encode ()-encode data using MIME base64
The header string is encoded before the type example: =? UTF-8? B?
After the title string is added:? =

For example:

$subject = "=? UTF-8? B? ". Base64_encode ($subject). "? =";

Add the above sentence to the code, so that the Chinese message headers sent are not garbled.
