Question

我想在电子邮件中同时发送html和纯文本。我找到this pretty straightforward tutorial但它使用mail（）函数发送电子邮件。如何转换此代码发送带有PHP Mailer类的电子邮件？

//specify the email address you are sending to, and the email subject
$email = 'email@example.com';
$subject = 'Email Subject';

//create a boundary for the email. This 
$boundary = uniqid('np');

//headers - specify your from email address and name here
//and specify the boundary for the email
$headers = "MIME-Version: 1.0\r\n";
$headers .= "From: Your Name \r\n";
$headers .= "To: ".$email."\r\n";
$headers .= "Content-Type: multipart/alternative;boundary=" . $boundary . "\r\n";

//here is the content body
$message = "This is a MIME encoded message.";
$message .= "\r\n\r\n--" . $boundary . "\r\n";
$message .= "Content-type: text/plain;charset=utf-8\r\n\r\n";

//Plain text body
$message .= "Hello,\nThis is a text email, the text/plain version.
\n\nRegards,\nYour Name";
$message .= "\r\n\r\n--" . $boundary . "\r\n";
$message .= "Content-type: text/html;charset=utf-8\r\n\r\n";

//Html body
$message .= "
 Hello,
This is a text email, the html version.

Regards,
Your Name";
$message .= "\r\n\r\n--" . $boundary . "--";

//invoke the PHP mail function
mail('', $subject, $message, $headers);

Answer 1

见下文：

$mail = new PHPMailer();

$mail->IsHTML(true);
$mail->CharSet = "text/html; charset=UTF-8;";
$mail->IsSMTP();

$mail->WordWrap = 80;
$mail->Host = "smtp.thehost.com"; 
$mail->SMTPAuth = false;

$mail->From = $from;
$mail->FromName = $from; // First name, last name
$mail->AddAddress($to, "First name last name");
#$mail->AddReplyTo("reply@thehost.com", "Reply to address");

$mail->Subject =  $subject;
$mail->Body =  $htmlMessage; 
$mail->AltBody  =  $textMessage;    # This automatically sets the email to multipart/alternative. This body can be read by mail clients that do not have HTML email capability such as mutt.

if(!$mail->Send())
{
  throw new Exception("Mailer Error: " . $mail->ErrorInfo);
}

PHPMailer中有一个函数：msgHTML()

# Minimum code to send an email:
$phpmailer = new PHPMailer();

$phpmailer->From = $from;
$phpmailer->FromName = $from_name;

$phpmailer->AddAddress( $to, $to_name );

$phpmailer->Subject = $subject;

$phpmailer->CharSet = 'UTF-8';

$phpmailer->msgHTML( $htmlMessage ); # <- right here!

# Use PHP's mail() instead of SMTP:
$phpmailer->IsMail();

$phpmailer->Send();

从HTML字符串创建消息。自动对内嵌图像和背景进行修改并通过转换HTML创建纯文本版本。覆盖$ this-＆gt; Body和$ this-＆gt; AltBody
中的任何现有值

试试这个：

$mail->SMTPDebug = 2;

调试级别

将 PHPMailer->SMTPDebug 属性设置为这些数字或常量（在 SMTP 类中定义）会导致不同数量的输出：

SMTP::DEBUG_OFF (0)：禁用调试（你也可以保留这个完全退出，0 是默认值）。
SMTP::DEBUG_CLIENT (1)：客户端发送的输出消息。
SMTP::DEBUG_SERVER (2)：作为 1，加上从服务器（这是最有用的设置）。
SMTP::DEBUG_CONNECTION (3)：作为 2，加上更多关于初始连接 - 此级别可以帮助诊断 STARTTLS 故障。
SMTP::DEBUG_LOWLEVEL (4)：为 3，加上更低级别信息，非常冗长，不用于调试 SMTP，仅用于低级问题。

除非您根本无法连接，否则您不需要使用高于 2 的级别 - 它只会使输出更冗长且更难以阅读。

请注意，在调用 send() 之前不会得到任何输出，因为在调用之前不会发生 SMTP 会话。
