php 发送带有 .csv 附件的 html 电子邮件答案

【问题标题】：php send html email with .csv attachmentphp 发送带有 .csv 附件的 html 电子邮件
【发布时间】：2012-05-08 17:05:05
【问题描述】：

我通过 php 发送电子邮件没问题。我想附上一个 .csv 文件以及提供的 HTML 电子邮件。我似乎无法找到如何做到这一点。我是否还必须在$headers 中包含某种内容类型以及附件的Content-Disposition？

$to = 'email@email.com';
$subject = 'A Subject Line';
$headers  = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";

$message = "
<html>
<head>
  <title>List of New Price Changes</title>
</head>
<body>";

$message .="HTML table";
$message .="</body></html>";

mail($to, $subject, $message, $headers);

 $fileatt_type = "text/csv";
$myfile = "myfile.csv";

        $file_size = filesize($myfile);
        $handle = fopen($myfile, "r");
        $content = fread($handle, $file_size);
        fclose($handle);

        $content = chunk_split(base64_encode($content));

        $message = "<html>
<head>
  <title>List of New Price Changes</title>
</head>
<body><table><tr><td>MAKE</td></tr></table></body></html>";

        $uid = md5(uniqid(time()));

        #$header = "From: ".$from_name." <".$from_mail.">\r\n";
        #$header .= "Reply-To: ".$replyto."\r\n";
        $header .= "MIME-Version: 1.0\r\n";
        $header .= "Content-Type: multipart/mixed; boundary=\"".$uid."\"\r\n\r\n";
        $header .= "This is a multi-part message in MIME format.\r\n";
        $header .= "--".$uid."\r\n";
        $header .= "Content-type:text/html; charset=iso-8859-1\r\n";
        $header .= "Content-Transfer-Encoding: 7bit\r\n\r\n";
        $header .= $message."\r\n\r\n";
        $header .= "--".$uid."\r\n";
        $header .= "Content-Type: text/csv; name=\"".$myfile."\"\r\n"; // use diff. tyoes here
        $header .= "Content-Transfer-Encoding: base64\r\n";
        $header .= "Content-Disposition: attachment; filename=\"".$myfile."\"\r\n\r\n";
        $header .= $content."\r\n\r\n";
        $header .= "--".$uid."--";

mail($to, $subject, $message, $header);

尝试根据您的情况修改代码。

它是否适用于简单的边界，例如“Bound bound bound”？
为什么要设置自己的边界？代码计算你一个不错的。
这是我在没有附件的电子邮件中收到的内容：MIME-Version: 1.0 Content-Type: multipart/mixed; boundary="==Multipart_Boundary_xaa04eec9f70b8e7b42496fa47f70257dx" This is a multi-part message in MIME format. --==Multipart_Boundary_xaa04eec9f70b8e7b42496fa47f70257dx Content-Type:text/html; charset="iso-8859-1" Content-Transfer-Encoding: 7bit --==Multipart_Boundary_xaa04eec9f70b8e7b42496fa47f70257dx Content-Type: text/csv; name="" Content-Transfer-Encoding: base64 TUFLRSxNT0RFTA0KQU1BTkEsSERDMTgyDQo= --==Multipart_Boundary_xaa04eec9f70b8e7b42496fa47f70257dx--
该代码用于一个附件。要发送不带附件的电子邮件，您需要更改并删除一些行。它仍然会发送电子邮件，但正如您所见，标题现在变得有点复杂和不必要。尝试使用文件:)
我相信这个答案现在已经过时了。我能够在这里找到问题的解决方案：stackoverflow.com/questions/30887610/…

【解决方案2】：

您将 HTTP 标头与邮件混淆了......您可能想要发送 multipart messages，但我不想重新实现它，而是使用类似 PHPMailer 的东西。

此代码适用于我。你可以试试这个。

<?php
$con = mysqli_connect('localhost', 'username', 'password', 'databasename');
if (!$con)
{
    die("error" . mysqli_connect_error());
}

error_reporting(E_ERROR);
$filename = "adhaar_info";
$sql = mysqli_query($con, "SELECT * FROM adhaar_info order by id desc limit 0,10");
$row = mysqli_fetch_assoc($sql);
$filename2='datas/'.$filename.'.csv';
$fp = fopen($filename2, "w");
$seperator = "";
$comma = "";
foreach ($row as $name => $value){$seperator .= $comma . '' . str_replace('', '""', $name);$comma = ",";}
$seperator .= "\n";
$seperator;
fputs($fp, $seperator);
mysqli_data_seek($sql, 0);
while ($row = mysqli_fetch_assoc($sql))
{
    $seperator = "";
    $comma = "";
    foreach ($row as $name => $value){$seperator .= $comma . '' . str_replace('', '""', $value);$comma = ",";}
    $seperator .= "\n";
    fputs($fp, $seperator);
}

fclose($fp);

$my_file = $filename2;
$path = "datas/";
$from_name = "solomon";
$from_mail = "pss@gmail.com";
$mailto = "pssworkcse@gmail.com";
$subject = "This is a mail with attachment.";
$message = "Hi,\r\n do you got attachment?\r\n\r\Solomon";
$replyto = "pssworkcse@gmail.com";
$file = $my_file;
$file_size = filesize($file);
$handle = fopen($file, "r");
$content = fread($handle, $file_size);
fclose($handle);
$content = chunk_split(base64_encode($content));
$uid = md5(uniqid(time()));
$name = basename($file);
$header = "From: " . $from_name . " <" . $from_mail . ">\r\n";
$header .= "Reply-To: " . $replyto . "\r\n";
$header .= "MIME-Version: 1.0\r\n";
$header .= "Content-Type: multipart/mixed; boundary=\"" . $uid . "\"\r\n\r\n";
$header .= "This is a multi-part message in MIME format.\r\n";
$header .= "--" . $uid . "\r\n";
$header .= "Content-type:text/plain; charset=iso-8859-1\r\n";
$header .= "Content-Transfer-Encoding: 7bit\r\n\r\n";
$header .= $message . "\r\n\r\n";
$header .= "--" . $uid . "\r\n";
$header .= "Content-Type: application/octet-stream; name=\"" . $filename2 . "\"\r\n"; 
$header .= "Content-Transfer-Encoding: base64\r\n";
$header .= "Content-Disposition: attachment; filename=\"" . $filename2 . "\"\r\n\r\n";
$header .= $content . "\r\n\r\n";
$header .= "--" . $uid . "--";
mail($mailto, $subject, "", $header)

?>
