如何在PHP中将邮件附件保存到服务器？ [英] How can I save email attachments to the server in PHP?

问题描述

在两天之内，我一直在和PHP的电子邮件阅读功能进行比较。我正在编写一个脚本来从邮箱读取邮件，并将任何附件保存到服务器上。如果你曾经做过类似的事情，你可能会明白我的痛苦： PHP不能很好地发送邮件！

I've been battling PHP's email reading functions for the better part of two days. I'm writing a script to read emails from a mailbox and save any attachments onto the server. If you've ever done something similar, you might understand my pain: PHP doesn't play well with email!

我已经连接到POP3服务器，我可以迭代文件。以下是代码的粗略概述：

I've connected to the POP3 server and I can iterate the files. Here's a rough outline of the code:

if (!$mbox = imap_open ("{myserver.com:110/pop3/notls}INBOX", "u", "p"))
    die ('Cannot connect/check mail! Exiting');

if ($hdr = imap_check($mbox)) 
    $msgCount = $hdr->Nmsgs;
else 
    die ("Failed to get mail");

foreach ($overview as $message) {
    $msgStruct = imap_fetchstructure($mbox, $message->msgno);

    // if it has parts, there are attachments that need reading
    if ($msgStruct->parts) {
        foreach ($msgStruct->parts as $key => $part) {
            switch (strtoupper($part->subtype)) {
                case 'GIF': case 'JPEG':case 'PNG':

                    //do something - but what?!

                    break;
            }
        }
    }
}

'我标记在我被卡住的地方。我可以使用 imap_fetchbody（$ mbox，$ message-> msgno，$ key + 1），但是这可以让我得到如下一些数据：

I've marked where I'm stuck. I can use imap_fetchbody($mbox, $message->msgno, $key+1) but that gets me a bunch of data like this:

...

我相信这是MIME数据。我需要它作为一个图像！我已经看到几个类在网络上轰炸声称要做所需的魔法。我不能让任何人上班。我不明白为什么我发现这么难！

I'm lead to believe that this is MIME data. I need it as an image! I've seen several classes bombing around the internet that claim to do the required wizardry. I can't get any of them to work. I don't understand why I'm finding this so hard!

简而言之，我正在寻找一些可以变成原始MIME字符串转换成实际数据。

In short, I'm looking for something that can turn a raw MIME string into real data.

推荐答案

我发现一个快速指南如何使用PHP处理电子邮件：这里。

I found a quick guide how to treat emails with PHP: here.

在该页面的底部有一个附件体 echo ：

At the bottom of that page there's a attachment-body echo:

if (substr($ContentType,0,4) == "text") {
echo imap_qprint($fileContent);
} else {
echo imap_base64($fileContent);
}

我想这是你可能需要的...

I guess this is what you might need...

（编辑：在你的情况下，如果它的图像总是你可以跳过如果部分，当然，保存文件而不是回显它：）

(edit: in your case if it's image always you can skip the if part. And of course, save the file instead of echoing it:)
