如何将使用TCPDF创建的pdf附加到mailto链接？

Question

我想将使用TCPDF创建的pdf文件附加到我的电子邮件中。

我就是这样做的：

$fileatt = $pdf->Output('file.pdf', 'E');

header("Location: mailto:someone@somepage.com?subject=my report&attachment=".$fileatt."&body=see attachment"); 

但是收到错误消息Warning: Header may not contain more than a single header

更新：

Fred -ii-建议使用Swiftmail解决此问题：

$ fileatt = $ pdf-＆gt;输出（＆＃39; quotation.pdf＆＃39;，＆＃39; E＆＃39;）;

require_once 'swiftmailer/lib/swift_required.php';

// Create the mail transport configuration
$transport = Swift_MailTransport::newInstance();

// Create the message
$message = Swift_Message::newInstance();
$message->setTo(array(
  "someone@somewhere.com" => "Someone",
));
$message->setSubject("This email is sent using Swift Mailer");
$message->setBody("You're our best client ever.");
$message->setFrom("someone@somewhere.com", "Your bank");

// Send the email
$mailer = Swift_Mailer::newInstance($transport);
$mailer->send($message);

$message->attach(
Swift_Attachment::$fileatt);

但我仍然无法弄清楚，如何将其与mailto结合起来
