发附件问题，mb_send_mail不可以，mail可以，为啥？

[thefirstwind]

很着急啊，
求解。
谢谢先
以下是我的程序：

$att_files = "/work/cgi-bin/prs/テストファイル.txt";
//$mine = "js";

//send_mail2($to, $subject, $text_body, $headers, $html_body="", $att_names="", $att_files="", $file_types="");

($attach = file_get_contents($filename)) Or die("Open Error: $filename");
$filename = basename($filename);
$ret = Attach_Mail($from, $to, $subject, $body, $filename, $attach, $mine);
}else{

}

对不起，上面这个垃圾代码太多，我把没用的注释掉了，

show me the error log.

[thefirstwind]

对不起，可能是我表述的不太清楚，
上面的程序是正确的，
我想全部送信处理使用mb_send_mail
也就是return mail(NULL, $subject, $mbody, $header);
替换成，
return mb_send_mail($to, $subject, $body, $header);

结果是上面的分支，原来使用mail送信的那个地方，改称mb_send_mail之后，发信可以，但是无法解析成附件。
不理解。

php版本5.0，按理说直接把mail替换成mb_send_mail是没有问题的。

把错误贴出来，

[thefirstwind]

没有人知道吗？

[li1229363]

你提问等待时间太早了，而且今天是周一。

mb_send_mail不是php标准的函数，所以，就是贴出了代码，一般人是没有时间帮你分析的

mail是php的标准函数，所以，可以发送成功是无可厚非的

[thefirstwind]

谢谢楼上，不过我还是想求个答案。
看了MIME的协议，根本没有思路就是瞎试，

[fredyj]

关注

手册上面看不出来什么 note里还有人说应该可以用。

你看看这个人说的是不是有帮助~

[thefirstwind]

very nice , 回家看看，谢谢楼上。

[peterxuxu]

$mbody .= "--$boundary--\n";多段文本应该是-==dddd==开头 -==dddd==结尾才对
而且内容编码后使用chuk函数分割一下最好。
另外其实并没有必要为编码犯愁采用BASE64 ENCODE一下就可以了
例如"Subject: =?gb2312?B?".base64_encode("subject")."?=";这样的代码可以使用任何编码（gb2312就是编码你可以换成UTF-8）

[thefirstwind]

楼上


对于boundary的写法我想我这里是没有问题的，
http://jp2.php.net/manual/ja/ref.mail.php


<?
$mime_boundary_2 = "1_".$mime_boundary;

$msg .= "Content-Type: multipart/alternative; boundary=\"".$mime_boundary_2."\"".$eol;

# Text Version
$msg .= "--".$mime_boundary_2.$eol;
$msg .= "Content-Type: text/plain; charset=iso-8859-1".$eol;
$msg .= "Content-Transfer-Encoding: 8bit".$eol.$eol;
$msg .= strip_tags(str_replace("<br>", "\n", $body)).$eol.$eol;

# HTML Version
$msg .= "--".$mime_boundary_2.$eol;
$msg .= "Content-Type: text/html; charset=iso-8859-1".$eol;
$msg .= "Content-Transfer-Encoding: 8bit".$eol.$eol;
$msg .= $body.$eol.$eol;

# New Subboundary Finished
$msg .= "--".$mime_boundary_2."--".$eol.$eol;

# Top-Boundary Finished
$msg .= "--".$mime_boundary."--".$eol.$eol;
?>



看来不是非要-==dddd==开头结尾的。



你说的那个chun函数应该是
<?php
$new_string = chunk_split(base64_encode($data));
?>
吧。我的程序里面有啊。


对于编码的问题，邮件文本采用EUC-JP编码，和文本采用SHIFT-JIS编码，这个是不变的。

谢谢楼上了。
