得到奇怪的结果在PHP邮件功能

Question

我正在使用此功能通过电子邮件向附件发送消息

function sendemail($to, $from, $subject, $filename, $attachment_name) {

    $random_hash = md5(date('r', time()));

    $headers = "From: $from\r\nReply-To: $from";

    $headers .= "\r\nContent-Type: multipart/mixed; boundary=\"PHP-mixed-" . $random_hash . "\"";

    $attachment = chunk_split(base64_encode(file_get_contents($filename)));

    $output = "
--PHP-mixed-$random_hash
Content-Type: multipart/alternative; boundary='\"PHP-alt-$random_hash\"'

Hello World!
This is the simple text version of the email message.


--PHP-alt-$random_hash
Content-Type: text/html; charset=\"UTF8\"
Content-Transfer-Encoding: 7bit


<h2>Hello World!</h2>
<p>This is the <b>HTML</b> version of the email message.</p>

--PHP-alt-$random_hash--

--PHP-mixed-$random_hash
Content-Type: application/zip; name=$attachment_name
Content-Transfer-Encoding: base64
Content-Disposition: attachment

$attachment
--PHP-mixed-$random_hash--";

    if (@mail($to, $subject, $output, $headers)) {
        echo 'good';
    } else {
        echo 'bad';
    }
}

但是这是我得到的实际消息的屏幕截图：

如何摆脱

--PHP-alt-a08184c8a852c31ac8c508fe6ca357d8
Content-Type: text/html; charset="UTF8"
Content-Transfer-Encoding: 7bit

在电子邮件中，实际上将其用作元

Answer 1

公共变量

$to = 'to@localhost.com';
$from = 'from@localhost.com';
$subject = 'Subject 123';
$body = '<b>Hello World</b>';
$filename = 'index.rar';

您的代码

function sendemail($to, $from, $subject, $body, $filename) {
    $random_hash = md5(date('r', time()));
    $headers = "From: $from\r\nReply-To: $from";
    $headers .= "\r\nContent-Type: multipart/mixed; boundary=\"PHP-mixed-" . $random_hash . "\"";
    $attachment = chunk_split(base64_encode(file_get_contents($filename)));
    $output = "
--PHP-mixed-$random_hash
Content-Type: multipart/alternative; boundary='\"PHP-alt-$random_hash\"'

" . strip_tags($body) . "

--PHP-alt-$random_hash
Content-Type: text/html; charset=\"UTF8\"
Content-Transfer-Encoding: 7bit

" . $body . "

--PHP-alt-$random_hash--

--PHP-mixed-$random_hash
Content-Type: application/zip; name=" . basename($filename) . "
Content-Transfer-Encoding: base64
Content-Disposition: attachment

$attachment
--PHP-mixed-$random_hash--";
    return mail($to, $subject, $output, $headers);
}
sendemail($to, $from, $subject, $body, $filename);
