【问题描述】：
#!/usr/bin/php -q
<?php
$savefile = "savehere.txt";
$sf = fopen($savefile, 'a') or die("can't open file");
ob_start();
// read from stdin
$fd = fopen("php://stdin", "r");
$email = "";
while (!feof($fd)) {
$email .= fread($fd, 1024);
}
fclose($fd);
// handle email
$lines = explode("\n", $email);
// empty vars
$from = "";
$subject = "";
$headers = "";
$message = "";
$splittingheaders = true;
for ($i=0; $i < count($lines); $i++) {
if ($splittingheaders) {
// this is a header
$headers .= $lines[$i]."\n";
// look out for special headers
if (preg_match("/^Subject: (.*)/", $lines[$i], $matches)) {
$subject = $matches[1];
}
if (preg_match("/^From: (.*)/", $lines[$i], $matches)) {
$from = $matches[1];
}
if (preg_match("/^To: (.*)/", $lines[$i], $matches)) {
$to = $matches[1];
}
} else {
// not a header, but message
$message .= $lines[$i]."\n";
}
if (trim($lines[$i])=="") {
// empty line, header section has ended
$splittingheaders = false;
}
}
/*$headers is ONLY included in the result at the last section of my question here*/
fwrite($sf,"$message");
ob_end_clean();
fclose($sf);
?>
这是我尝试的一个例子。问题是我在文件中得到了太多。 这是写入文件的内容：（如您所见，我刚刚向它发送了一堆垃圾）

我在四处搜索时发现了这个，但不知道如何实现或在我的代码中插入的位置，或者它是否可以工作。
preg_match("/boundary=\".*?\"/i", $headers, $boundary);
$boundaryfulltext = $boundary[0];
if ($boundaryfulltext!="")
{
$find = array("/boundary=\"/i", "/\"/i");
$boundarytext = preg_replace($find, "", $boundaryfulltext);
$splitmessage = explode("--" . $boundarytext, $message);
$fullmessage = ltrim($splitmessage[1]);
preg_match('/\n\n(.*)/is', $fullmessage, $splitmore);
if (substr(ltrim($splitmore[0]), 0, 2)=="--")
{
$actualmessage = $splitmore[0];
}
else
{
$actualmessage = ltrim($splitmore[0]);
}
}
else
{
$actualmessage = ltrim($message);
}
$clean = array("/\n--.*/is", "/=3D\n.*/s");
$cleanmessage = trim(preg_replace($clean, "", $actualmessage));
那么，我怎样才能将电子邮件的纯文本区域放入我的文件或脚本中以进行进一步处理？？
提前致谢。 stackoverflow 很棒！
【问题讨论】：
-
这是完整的电子邮件吗？它缺少
Content-Type: multipart/mixed标头，它应该指定边界字符串是什么（您找到的代码需要）。 -
这只是电子邮件中保存到文件的部分。这是我使用第一个代码示例所能得到的最精简的。
-
边界标头对于能够解析您的电子邮件很重要，因为它指定了电子邮件的每个部分开始和结束的位置。没有它，您所能做的就是猜测，并且您知道他们所说的假设... ;) 例如，对于您引用的电子邮件，应该有一个标题，如：
Content-Type: multipart/mixed; boundary="----=_NextPart_000_0163_01CB4EA5.46466520" -
来自不同的基于 PC 的电子邮件客户端或流行的免费电子邮件帐户的界限是否相同？
-
我将 headers var 添加到文件 write 并编辑了我的问题，以便为你们/gals 添加该信息...
