Question

是否可以将dompdf生成的PDF发送到电子邮件，而无需在服务器上保存PDF并且不使用梨类？

我发现只有以下方面的解决方案： 1）在服务器上保存pdf，然后将其添加为附件或 2）使用一些梨类

这两个都不适合我。我在变量中有pdf：

$pdf = $dompdf->output();

我认为你应该能够对你在$ pdf中存储为字符串的PDF信息进行64位编码，直接插入到多部分mime电子邮件中，然后使用PHP的mail（）函数发送它，如下所示：

    // to, from, subject, message body, attachment filename, etc.
    $to = "to@to.com";
    $from = "from@from.com";
    $subject = "subject";
    $message = "this is the message body";        
    $fname="nameofpdfdocument.pdf";

    $headers = "From: $from"; 
    // boundary 
    $semi_rand = md5(time()); 
    $mime_boundary = "==Multipart_Boundary_x{$semi_rand}x"; 

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

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

    // preparing attachment            
        $data=$pdf;
        $data = chunk_split(base64_encode($data));
        $message .= "Content-Type: {\"application/pdf\"};\n" . " name=\"$fname\"\n" . 
        "Content-Disposition: attachment;\n" . " filename=\"$fname\"\n" . 
        "Content-Transfer-Encoding: base64\n\n" . $data . "\n\n";
        $message .= "--{$mime_boundary}\n";


    // send
    //print $message;

    $ok = @mail($to, $subject, $message, $headers, "-f " . $from);

将生成的pdf（带有dompdf）发送到电子邮件，而不保存在服务器上和没有梨类
