PHPMailer 字符编码问题 [英] PHPMailer character encoding issues
问题描述
我尝试使用PHPMailer发送注册、激活.等邮件给用户:
I try to use PHPMailer to send registration, activation. etc mail to users:
require("class.phpmailer.php");
$mail -> charSet = "UTF-8";
$mail = new PHPMailer();
$mail->IsSMTP();
$mail->Host = "smtp.mydomain.org";
$mail->From = "name@mydomain.org";
$mail->SMTPAuth = true;
$mail->Username ="username";
$mail->Password="passw";
//$mail->FromName = $header;
$mail->FromName = mb_convert_encoding($header, "UTF-8", "auto");
$mail->AddAddress($emladd);
$mail->AddAddress("mytest@gmail.com");
$mail->AddBCC('mytest2@mydomain.org', 'firstadd');
$mail->Subject = $sub;
$mail->Body = $message;
$mail->WordWrap = 50;
if(!$mail->Send()) {
echo 'Message was not sent.';
echo 'Mailer error: ' . $mail->ErrorInfo;
}
$message 包含拉丁字符.不幸的是，所有网络邮件(gmail、webmail.mydomain.org、emailaddress.domain.xx)都使用不同的编码.
The $message contains latin characters. Unfortunately all webmail (gmail, webmail.mydomain.org, emailaddress.domain.xx) is using a different coding.
如何强制使用 UTF-8 编码以在所有邮箱上显示完全相同的邮件?
How can I force to use UTF-8 coding to show my mail exactly the same on all mailboxes?
我尝试转换邮件标题宽度 mb_convert_encoding()，但没有成功.
I tried to convert the mail header width mb_convert_encoding(), but without luck.
推荐答案
如果您 100% 确定 $message 包含 ISO-8859-1，您可以使用 utf8_encode 正如大卫所说.否则使用 mb_detect_encoding 和 mb_convert_encoding 在 $message 上.
If you are 100% sure $message contain ISO-8859-1 you can use utf8_encode as David says. Otherwise use mb_detect_encoding and mb_convert_encoding on $message.
还要注意
$mail -> charSet = "UTF-8";
应替换为:
$mail->CharSet = 'UTF-8';
和放在之后类的实例化(在new之后).属性区分大小写！请参阅列表中的 PHPMailer 文档准确拼写.
And placed after the instantiation of the class (after the new). The properties are case sensitive! See the PHPMailer doc fot the list & exact spelling.
此外，PHPMailer 的默认编码是 8bit，对于 UTF-8 数据可能会出现问题.要解决此问题，您可以执行以下操作:
Also the default encoding of PHPMailer is 8bit which can be problematic with UTF-8 data. To fix this you can do:
$mail->Encoding = 'base64';
请注意，'quoted-printable' 在这些情况下也可能会起作用(甚至可能是 'binary').有关更多详细信息，您可以阅读 RFC1341 - Content-Transfer-Encoding Header Field.
Take note that 'quoted-printable' would probably work too in these cases (and maybe even 'binary'). For more details you can read RFC1341 - Content-Transfer-Encoding Header Field.
