發送電子郵件附件收到空白文件

Question

我試圖添加使用PHP發送電子郵件附件，文件附件工作正常，但附件文件打開空白document.How解決這個問題。下面提到我的代碼。

$from_email = 'sender_mail@example.com'; //sender email 
$recipient_email = 'manosk24@gmail.com'; //recipient email 
$subject = 'Test mail'; //subject of email 
$message = 'This is body of the message'; //message body 

$filename = "file1.pdf"; 
$path = $_SERVER['DOCUMENT_ROOT'] . "/mail-function/upload/"; 
$file = $path.$filename; 
$file_size = filesize($file); 
$handle = fopen($file, "rb"); 
$content = fread($handle, $file_size); 
fclose($handle); 
$content = chunk_split(base64_encode($content)); 


$boundary = md5(uniqid(time())); 
//header 
$headers = "MIME-Version: 1.0\r\n"; 
$headers .= "From:" . $from_email . "\r\n"; 
$headers .= "Reply-To: " . $user_email . "" . "\r\n"; 
$headers .= "Content-Type: multipart/mixed; boundary = $boundary\r\n\r\n"; 

//plain text 
$body = "--$boundary\r\n"; 
$body .= "Content-Type: text/plain; charset=ISO-8859-1\r\n"; 
$body .= "Content-Transfer-Encoding: base64\r\n\r\n"; 
$body .= chunk_split(base64_encode($message)); 

//attachment 
$body .= "--$boundary\r\n"; 
$body .="Content-Type: application/pdf; name=" . $filename . "\r\n"; 
$body .="Content-Disposition: attachment; filename=" . $filename . "\r\n"; 
$body .="Content-Transfer-Encoding: base64\r\n"; 
$body .="X-Attachment-Id: " . rand(1000, 99999) . "\r\n\r\n"; 
$body .= $encoded_content; 

$sentMail = @mail($recipient_email, $subject, $body, $headers); 
if ($sentMail) { //output success or failure messages 
    die('Thank you for your email'); 
} else { 
    die('Could not send mail! Please check your PHP mail configuration.'); 
} 

對不起，我的拼寫錯誤..

試試這個代碼，

$filename = "file1.pdf"; 
    $file = $path . "/" . $filename; 
    $message ="my message"; 
    $file_size = filesize($file); 
    $handle = fopen($file, "r"); 
    $content = fread($handle, $file_size); 
    fclose($handle); 
    $content = chunk_split(base64_encode($content)); 

    // 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; 

    // main header (multipart mandatory) 
    $headers = "From: name <test@test.com>" . $eol; 
    $headers .= "MIME-Version: 1.0" . $eol; 
    $headers .= "Content-Type: multipart/mixed; boundary=\"" . $separator . "\"" . $eol; 
    $headers .= "Content-Transfer-Encoding: 7bit" . $eol; 
    $headers .= "This is a MIME encoded message." . $eol; 

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

    //SEND Mail 
    if (mail($mailto, $subject, "", $headers)) { 
     echo "mail send ... OK"; // or use booleans here 
     } else { 
     echo "mail send ... ERROR!"; 
     } 

我希望這會有所幫助。
