是否可以将 dompdf 生成的 PDF 发送到电子邮件,而不在服务器上保存 PDF 并且不使用 pear 类?
我发现解决方案仅适用于:1)将 pdf 保存在服务器上,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();
我认为您应该能够对存储为 $pdf 中的字符串的 PDF 信息进行 base64 编码,直接插入到多部分 mime 电子邮件中,然后使用 PHP 的 mail() 函数将其发送,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);
