Solution to the garbled title when the mail function of php sends UTF-8 encoded Chinese mail: 1. Make the text in the subject conform to the specifications of RFC 2047; 2. Add [content-type] to the headers; 3. , Correctly configure the host used to send emails.

What should I do if the title is garbled when the PHP mail function sends UTF-8 encoded Chinese emails?

Solution to the garbled title of the mail function when sending UTF-8 encoded Chinese emails:

1. Use PEAR’s Mail class

PEAR’s Mail class allows you to choose to use sendmail or SMTP to send letters. Such a packaged interface is easy to use, and you don’t need to reinvent it yourself. wheel.

2. Regarding the garbled characters of the subject in the headers

Do not put any text other than the iso-8859-1 code directly into the subject , the correct way is to make the text in the subject comply with the specifications of RFC 2047. Assume that the encoding of the text in your subject is GB2312, then the correct subject should be in this format

$headers['subject'] = '=?GB2312?B?' . base64_encode('标题文字') . '?=';

If it is UTF-8, just replace the GB2312 at the beginning with UTF-8. It is recommended to use GB2312 encoding in the title, because MTA differentiation is really serious. Most MSPs use self-developed MTAs, and I believe that most domestic MTAs can support GB2312 encoding anyway.

If it is sent to a foreign MSP, it is recommended that you use base64-encoded UTF-8 text at the subject, because they probably do not support GB2312 encoding.

3. Be sure to add content-type in the headers

The content-type in the headers of the email is similar to that of the web page, and it is alsotext/plain; charset=gb2312 This format. This option is mainly meaningful for clients that receive emails. It can avoid garbled characters on the client. Some Webmails will also encode and convert the content of the email based on the settings here to display it correctly. You can imagine what happens when you use gb2312 encoding to send it to the email address of .com.tw .

4. Correctly configure the host you use to send emails

1) Be sure to configure reverse resolution, because most non-fixed IPs cannot be reversed. Directional analysis, some anti-spam policies use this as a basis for judgment.

2) Be sure to configure MX parsing, the same reason as above.

3) Make sure your return path can receive bounced emails, otherwise your email sending server may enter the receiving end's blacklist.

$subject = stripslashes($the_post['Title']); 
$headers = "MIME-Version: 1.0\r\n"; 
$headers .= "Content-type: text/plain; charset=utf-8\r\n"; 
$headers .= "Content-Transfer-Encoding: 8bit\r\n"; 
$message = stripslashes(strip_tags($the_post['Content'])); 
mail($to, $subject, $message, $headers);

Use the function firstbase64_encode()—Use MIME base64 to encode the data

Add the encoding type before the title string, for example: =?UTF-8 ?B?

Add after the title string: ?=

For example:

<?php  
 $to = "clairelume@qq.com"; //将此电子邮件地址改为自己的。  
 $name = $_POST[&#39;name&#39;];  
 $email = $_POST[&#39;email&#39;];  
 $subject = "来自博客读者的邮件";  
 $subject = "=?UTF-8?B?".base64_encode($subject)."?=";  
 $headers = "MIME-Version: 1.0\r\n";  
 $headers .= "Content-type: text/plain; charset=utf-8\r\n";  
 $headers .= "Content-Transfer-Encoding: 8bit\r\n";  
 $message = $_POST[&#39;message&#39;];  
 mail($to,$subject,$message,"From: ".$email."",$headers);  
 echo &#39;OK &#39;.$name.&#39;, 您的邮件已发送。&#39;;  
?>

In this way, the title of the Chinese email sent is not It's garbled.
