Question

我正在使用管道编程来向脚本发送电子邮件。使用此脚本，我可以成功地将整个电子邮件保存为我的服务器上的.txt文件。剩下要做的唯一事情是弄清楚如何保存电子邮件附带的任何附件。（此电子邮件地址仅提供给一个受信任的来源，因此安全性不是问题）

将整个电子邮件另存为.txt文件的工作代码：

$fd = fopen("php://stdin", "r");
$email = ""; // This will be the variable holding the data.
while (!feof($fd)) {
$email .= fread($fd, 1024);
}
fclose($fd);
/* Saves the data into a file */
$fdw = fopen("/home/lmshost22/public_html/pipemail.txt", "w+");
fwrite($fdw, $email);
fclose($fdw);

任何人都可以帮我解决只需提取附件的代码（将始终是.csv文件）并将其保存在我的服务器上吗？

以下是.txt文件为附件显示的代码：

Answer 1

附件意味着邮件是MIME / Multipart，并且设置了boundary标头，用于界定各种邮件部分。例如：
```
Content-Type: multipart/mixed;
    boundary="b1_bb1b331cd6dafa1dc6a19e3b2e090b07"
```
所以你想首先通过以下方式找到：
```
preg_match('/boundary="(.*)"/', $message, $matches);
```

消息除以--与边界连接，然后是特定于该部分的标题，空白行，然后是数据。例如：

--b1_bb1b331cd6dafa1dc6a19e3b2e090b07
Content-Type: application/pdf; name="Invoice-37272.pdf"
Content-Transfer-Encoding: base64
Content-Disposition: attachment; filename="Invoice-37272.pdf"

// base64 data here //

邮件以'--' . $boundary . '--'终止，例如：--b1_bb1b331cd6dafa1dc6a19e3b2e090b07--

因此，您可以使用这两个信息将您的消息分解为其组成部分并查找/保存附件。
