Question

我尝试使用php添加发送电子邮件附件，文件附件工作正常但附件文件打开空白文档。如何解决此问题.Below提到了我的代码。

$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.');
}

对不起我的拼写错误..

试试这段代码，

    $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!";
      }

我希望它会有所帮助。
