問題描述

=?UTF-8?GAMEFORCE 會(huì)員更改密碼通知?GAMEFORCE 會(huì)員更改密碼通知?= , 用phpmailer發(fā)送的郵件的標(biāo)題總是帶這些額外的字符。

問題出現(xiàn)的環(huán)境背景及自己嘗試過哪些方法

$mail->CharSet = "utf-8"，$mail->Subject = "=?UTF-8?B?" . base64_encode($subject) . "?=";
有試過設(shè)置字符集，但是郵件標(biāo)題還是帶這些字符。

$mail = new Mail_PHPMailer();
$mail->CharSet = "utf-8";
$mail->IsSMTP();
$mail->SMTPAuth = true;
$mail->Host = $config['hostname'];
$mail->Username = $config['username'];
$mail->Password = $config['password'];

$mail->SetFrom($config['username']);
$mail->AddAddress($email);
$mail->Subject = "=?UTF-8?B?" . base64_encode($subject) . "?=";

$mail->MsgHTML($content);
return $mail->Send();
