PHP将电子邮件添加到电子邮件

Question

我已成功在网站上创建了PDF文件。我想要做的就是将该pdf作为附件发送到电子邮件中。到目前为止，似乎我已经成功连接的文件但试图打开附件Acrobat Reader软件给我这个错误消息时：

Acrobat could not open 'example2.pdf' because it is either not a supported type or because the file has been damaged (for example, it was sent as an email attachment and wasn't correctly decoded) 

我觉得这个错误消息击中了要害，下面是我的代码有谁知道需要改变什么？感谢提前:)

$to = "me@domain"; 
$from = "me@domain.com"; 
$subject = "send email with pdf attachment"; 
$message = "<p>Please see the attachment.</p>"; 
// a random hash will be necessary to send mixed content 
$separator = md5(time()); 
// carriage return type (we use a PHP end of line constant) 
$eol = PHP_EOL; 
// attachment name 
$filename = "example.pdf"; 
// encode data (puts attachment in proper format) 
$attachment = chunk_split(base64_encode("/include/pdf.php?reportid=849980")); 
// main header (multipart mandatory) 
$headers = "From: ".$from.$eol; 
$headers .= "MIME-Version: 1.0".$eol; 
$headers .= "Content-Type: multipart/mixed; boundary=\"".$separator."\"".$eol.$eol; 
$headers .= "Content-Transfer-Encoding: 7bit".$eol; 
$headers .= "This is a MIME encoded message.".$eol.$eol; 
// message 
$headers .= "--".$separator.$eol; 
$headers .= "Content-Type: text/html; charset=\"iso-8859-1\"".$eol; 
$headers .= "Content-Transfer-Encoding: 8bit".$eol.$eol; 
$headers .= $message.$eol.$eol; 
// attachment 
$headers .= "--".$separator.$eol; 
$headers .= "Content-Type: application/octet-stream; name=\"".$filename."\"".$eol; 
$headers .= "Content-Transfer-Encoding: base64".$eol; 
$headers .= "Content-Disposition: attachment".$eol.$eol; 
$headers .= $attachment.$eol.$eol; 
$headers .= "--".$separator."--"; 
// send message 
mail($to, $subject, "", $headers); 

Answer 1

$filename = "example.pdf"; 
// encode data (puts attachment in proper format) 
$attachment = chunk_split(base64_encode("/include/pdf.php?reportid=849980")); 

看起来是你的问题。您的附件似乎是PDF，而是一个PHP页面...也需要二进制（rb）读入pdf的文件内容，如下所示：

$filename = 'example.pdf'; 
$fileloc = '/path/to/pdf/'.$filename; 

$filehandle = fopen($fileloc, 'rb'); 
$data = fread($filehandle, filesize($fileloc)); 
fclose($filehandle);     

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