php邮件特殊字符utf8

Question

我有以下脚本：

<?php
    $subject = "Testmail — Special Characters";
    $msg = "Hi there,\n\nthis isn’t something easy.\n\nI haven’t thought that it’s that complicated!";

    mail($to,$subject,$msg,$from."\nContent-Type: text/plain; charset=UTF-8\nContent-Transfer-Encoding: 8bit\n");
?>

在电子邮件中：

主题：Testmail ? Special Characters

主体：

Hi there,

this isn?t something easy.

I haven?t thought that it?s that complicated!

我尝试了很多东西，但我已经没有任何想法了。 你能帮助我吗？你有没有得到这个工作？

谢谢！

Answer 1

你试过iconv_set_encoding吗？

这应该可行：

<?php
 iconv_set_encoding("internal_encoding", "UTF-8");

$subject = "Testmail — Special Characters";
$msg = "Hi there,\n\nthis isn’t something easy.\n\nI haven’t thought that it’s that complicated!";

mail(utf8_decode($to), utf8_decode($subject), utf8_decode($msg), utf8_decode($from)."\nContent-Type: text/plain; charset=UTF-8\nContent-Transfer-Encoding: 8bit\n");?>

Answer 2

虽然iconv_set_encoding 对我不起作用，但以下方法对我有用：

// Force PHP to use the UTF-8 charset
header('Content-Type: text/html; charset=utf-8'); 

// Define and Base64 encode the subject line
$subject_text = 'Test email with German Umlauts öäüß';
$subject = '=?UTF-8?B?' . base64_encode($subject_text) . '?=';

// Add custom headers
$headers = 'Content-Type: text/plain; charset=utf-8' . "\r\n";
$headers .= 'Content-Transfer-Encoding: base64';

// Define and Base64 the email body text
$message = base64_encode('This email contains German Umlauts öäüß.');

// Send mail with custom headers
if (mail('recipient@domain.com', $subject, $message, $headers)) {
    echo 'Email has been sent!';
} else {
    echo 'Oops, something gone wrong!';
}

Answer 3

使用’ 代替'。

例子：

The dog’s bone.

确保将内容类型从 text/plain 更改为 text/html。
