使用 PHP mail() 函数附加文件并从下载邮件中读取该文件时出现问题

Question

我正在使用 PHP 邮件功能通过 Attachemnet 发送邮件。我成功地将文档附加到邮件中，并在邮件中收到了它。我的问题是当我尝试阅读文档时出现错误。如果我下载了文档并打开文档我看不到附件中的文本。这是编码...

$fileatt = '../'.$_POST['path']; // Path to the file
  $fileatt_type = "application/octet-sdiveam"; // File Type
  $fileatt_name = $_POST['attachfile']; 
  $email_from = '[email protected]'; // Who the email is from
  $email_subject = $_POST['Subject']; // The Subject of the email
  $email_txt = $_POST['Subject']; // Message that the email has in it

  $email_to = $_POST['To']; // Who the email is to

   $headers = "From: ".$email_from;

  $file = fopen($fileatt,'rb');
  $data = fread($file,filesize($fileatt));
  fclose($file);

  $semi_rand = md5(time());
  $mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";

  $headers .= "\nMIME-Version: 1.0\n" .
  "Content-Type: multipart/mixed;\n" .
  " boundary=\"{$mime_boundary}\"";

  $email_message .= "This is a multi-part message in MIME format.\n\n" .
  "--{$mime_boundary}\n" .
  "Content-Type:text/html; charset=\"iso-8859-1\"\n" .
  "Content-divansfer-Encoding: 7bit\n\n" .
  $email_message . "\n\n";

  $data = chunk_split(base64_encode($data));

  $email_message .= "--{$mime_boundary}\n" .
  "Content-Type: {$fileatt_type};\n" .
  " name=\"{$fileatt_name}\"\n" .
  //"Content-Disposition: attachment;\n" .
  //" filename=\"{$fileatt_name}\"\n" .
  "Content-divansfer-Encoding: base64\n\n" .
  $data . "\n\n" .
  "--{$mime_boundary}--\n";


  $ok = @mail($email_to, $email_subject, $email_message, $headers);

这是正确的方法吗？为什么我无法阅读该文档？我不知道。请帮助我。谢谢提前。

已解决：

问题是拼写错误。
Content-divansfer-Encoding： 应为Content-Transfer-Encoding：

我建议使用 pear 的 mail 和 mail_mime 库来使这个过程变得更加容易和干净。
