用php附件发送电子邮件，内容为php

Question

我是新来的php。我需要发送电子邮件与pdf附件。我可以发送附件的电子邮件。但无法打开PDF。我得到这样的一些错误

“Acrobat无法识别'file_name'，因为它不是受支持的文件类型，或者是因为文件已损坏（例如，它是作为电子邮件附件发送的，而不是正确解码）...“

如果有人能帮我解决这个问题，那会很好。谢谢！

这里是我的代码：

$to = 'form@kronova.in, ' . $Email; 
$subject = 'ABC :: Admission Form Details'; 
$repEmail = 'form@kronova.in'; 

$fileName = 'ABC-Admission.pdf'; 
$fileatt = $pdf->Output($fileName, 'E'); 
$attachment = chunk_split($fileatt); 
$eol = PHP_EOL; 
$separator = md5(time()); 

$headers = 'From: Principal abc <'.$repEmail.'>'.$eol; 
$headers .= 'MIME-Version: 1.0' .$eol; 
$headers .= "Content-Type: multipart/mixed; boundary=\"".$separator."\""; 

$message = "--".$separator.$eol; 
$message .= "Content-Transfer-Encoding: 7bit".$eol.$eol; 
$message .= "Thanks for filling online application form. Your online admission registration number is E0000". mysql_insert_id() . "." .$eol; 

$message .= "--".$separator.$eol; 
$message .= "Content-Type: text/html; charset=\"iso-8859-1\"".$eol; 
$message .= "Content-Transfer-Encoding: 8bit".$eol.$eol; 

$message .= "--".$separator.$eol; 
$message .= "Content-Type: application/pdf; name=\"".$fileName."\"".$eol; 
$message .= "Content-Transfer-Encoding: base64".$eol; 
$message .= "Content-Disposition: attachment".$eol.$eol; 
$message .= $attachment.$eol; 
$message .= "--".$separator."--"; 

if (mail($to, $subject, $message, $headers)){ 
echo "Email sent"; 
} 

else { 
echo "Email failed"; 
} 

Answer 1

试试这个：

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

而不是

$attachment = chunk_split($fileatt);
