如何在 PHP 中使用邮件标头字符串中的编码类型来解码邮件标头字符串

我正在 PHP 中创建一个小型的、基于 Web 的邮件客户端，并注意到许多电子邮件主题和内容如下所示：

=?ISO-8859-1?Q?Everything_for_=A35_-_Box_Sets,_Games_?= =?ISO-8859-1?Q?and_CD_Soundtracks...hurry,_ends_soon?=
=?utf-8?B?UGxheS5jb206IE9uZSBEYXkgT25seSDigJMgT3V0IG9mIHRoaXMgV29ybGQgRGVhbHMh?=
=?windows-1252?Q?Jon,_delivery_on_us_&_earn_=A35_credit_or_50_prints?=

有没有人有任何解码它们以便正确显示的想法？

I'm creating a small, web based, mail client in PHP and noticed that a number of email Subjects and Contents appear as follows:

=?ISO-8859-1?Q?Everything_for_=A35_-_Box_Sets,_Games_?= =?ISO-8859-1?Q?and_CD_Soundtracks...hurry,_ends_soon?=
=?utf-8?B?UGxheS5jb206IE9uZSBEYXkgT25seSDigJMgT3V0IG9mIHRoaXMgV29ybGQgRGVhbHMh?=
=?windows-1252?Q?Jon,_delivery_on_us_&_earn_=A35_credit_or_50_prints?=

Does anyone have any ideas for decoding them so they display correctly?

这是一个 RFC 2047 编码字。它由 mb_decode_mimeheader 函数解码。

这是主要用于标头的 MIME 编码字符串。您可以找到很多可以处理此问题的库。例如，获取 PEAR::mail 并使用此函数，

Mail_mimeDecode::_decodeHeader()

This is MIME-encoded string mainly used for headers. You can find lots of libraries that can handle this. For example, get PEAR::mail and use this function,

Mail_mimeDecode::_decodeHeader()

这是一个老问题，但最近我在解析电子邮件时遇到了这个问题。
当使用函数 imap_header_info 打印标题信息时，显示以下数组：

stdClass Object
(
    [subject] => =?Windows-1252?Q?field_name_-_need___`at_risk=92____into_t?= =?Windows-1252?Q?he_label_(_some_content_to_)_?=
)

然而，原来的主题是“字段名称 - 需要在风险中进入标签（某些内容）”，

为了解决这个问题，函数 imap_mime_header_decode
必须在循环中使用才能生成正确的文本：

$header = imap_headerinfo($email_obj, $email_ref_number, 0);
$elements = imap_mime_header_decode($header->subject);
$email_subject = '';
if ( ! empty($elements)) {
    foreach ($elements AS $e_part) {
        if (isset($e_part->text)) {
            $email_subject .= $e_part->text;
        }
    }
}
echo $email_subject;

This is an old question but recently I came across this issue while parsing the emails.
When printing the header info using function imap_header_info, the following array was shown:

stdClass Object
(
    [subject] => =?Windows-1252?Q?field_name_-_need___`at_risk=92____into_t?= =?Windows-1252?Q?he_label_(_some_content_to_)_?=
)

However, the original subject was "field name - need at risk into the label (some content to)"

In order to fix this issue, the function imap_mime_header_decode
has to be used within a loop to generate the correct text:

$header = imap_headerinfo($email_obj, $email_ref_number, 0);
$elements = imap_mime_header_decode($header->subject);
$email_subject = '';
if ( ! empty($elements)) {
    foreach ($elements AS $e_part) {
        if (isset($e_part->text)) {
            $email_subject .= $e_part->text;
        }
    }
}
echo $email_subject;
