PHP发送带有附件的电子邮件

php

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";
}

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。

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”;
}
