PHP发送带有附件的电子邮件

我似乎找不到我编写的应该发送带有附件的电子邮件的php函数的问题。我已经为此苦苦挣扎了一段时间了。

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";

}

问题是邮件的消息与文件混合在一起并作为附件发送。

回答:

Artefacto让我更加关注输出,并且找到了解决方法:

函数myMail($ to,$ subject,$ mail_msg,$ filename,$ contentType,$ pathToFilename){

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

$ headers =“发件人:webmaster@mysite.com \ r \ n回复至:”。$ to;

$ headers。=“” \ r \ nContent-Type:multipart / mixed; boundary = \“ PHP-mixed-”。$ random_hash。“ \”“;

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

ob_start();

回声“

--PHP-mixed- $ random_hash

内容类型:多部分/替代;boundary = \“ PHP-alt- $ random_hash \”

--PHP-alt- $ random_hash

内容类型:文本/纯文本;charset = \“ utf-8 \”

内容传输编码:7bit

$ mail_msg

--PHP-alt- $ random_hash--

--PHP-mixed- $ random_hash

内容类型:$ contentType; 名称= \“ $文件名\”

内容传输编码:base64

内容处置:附件

$附件

--PHP-mixed- $ random_hash--

“;

$ message = ob_get_clean();

$ fh = fopen('log.txt','w');

fwrite($ fh,$ message);

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

返回$ mail_sent吗?“邮件已发送”:“邮件失败”;

}
