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()));
$headers = "From: webmaster@\r\nReply-To: ".$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：
