我似乎找不到我编写的此php函数的问题,该函数应该发送带有附件的电子邮件。我已经为此苦苦挣扎了一段时间。
function myMail($to, $subject, $mail_msg, $filename, $contentType){
$random_hash = md5(date('r', time()));
$headers = "From: [email protected]\r\nReply-To: ".$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 $mail_sent ? "Mail sent" : "Mail failed";
}
编辑问题是邮件的消息与文件混合在一起并作为附件发送。
参考方案
我刚刚看了几封电子邮件,但我注意到最终的附件边界以“-”结尾,而开始边界标记没有。在您的代码中,您具有:
--PHP-mixed-$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--
