我似乎无法找到这个我写的php函数的问题,应该发送带附件的电子邮件.我已经挣扎了很长一段时间.

function myMail($to, $subject, $mail_msg, $filename, $contentType){

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

$headers = "From: webmaster@example.com\r\nReply-To: ".$to;

$headers .= "\r\nContent-Type: ".$contentType.

"; boundary=\"PHP-mixed-".$random_hash."\"";

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

ob_start();

echo "

--PHP-mixed-$random_hash

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

--PHP-alt-$random_hash

Content-Type: text/plain; charset=\"utf-8\"

Content-Transfer-Encoding: 7bit

$mail_msg

--PHP-alt-$random_hash

--PHP-mixed-$random_hash--

Content-Type: text/plain; name=\"$filename\"

Content-Transfer-Encoding: base64

Content-Disposition: attachment

$attachment

--PHP-mixed-$random_hash--

";

$message = ob_get_clean();

$mail_sent = @mail( $to, $subject, $message, $headers );

return $mail_sent ? "Mail sent" : "Mail failed";

}

编辑问题是邮件的消息与文件混合并作为附件发送.

解决方法:

我刚刚查看了几封电子邮件,并注意到最终的附件边界以’ – ‘结尾,而开放边界标记则没有.在您的代码中,您有：

--PHP-mixed-$random_hash--

Content-Type: text/plain; name=\"$filename\"

Content-Transfer-Encoding: base64

Content-Disposition: attachment

$attachment

--PHP-mixed-$random_hash--

也许它应该是：

--PHP-mixed-$random_hash

Content-Type: text/plain; name=\"$filename\"

Content-Transfer-Encoding: base64

Content-Disposition: attachment

$attachment

--PHP-mixed-$random_hash--

看看这里的例子：
