用php附件發送電子郵件，內容爲php

Question

我是新來的php。我需要發送電子郵件與pdf附件。我可以發送附件的電子郵件。但無法打開PDF。我得到這樣的一些錯誤

「Acrobat無法識別'file_name'，因爲它不是受支持的文件類型，或者是因爲文件已損壞（例如，它是作爲電子郵件附件發送的，而不是正確解碼）...「

如果有人能幫我解決這個問題，那會很好。謝謝！

這裏是我的代碼：

$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

試試這個：

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

而不是

$attachment = chunk_split($fileatt);
