【中文标题】使用 PHP Mail() 发送附件？【英文标题】：Send attachments with PHP Mail()? 【发布时间】：2012-08-31 08:22:14 【问题描述】：我需要通过邮件发送 pdf，可以吗？
$to = "xxx";
$subject = "Subject" ;
$message = 'Example message with <b>html</b>';
$headers = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
$headers .= 'From: xxx <xxx>' . "\r\n";
mail($to,$subject,$message,$headers);
我错过了什么？
【问题讨论】：
用mail()功能发送附件比你想象的要难，为了你的时间，尝试使用phpMailer
或者你可以直接链接到它？
@mihai lorga 这不需要服务器端安装吗？如果没有任何扩展或插件也可能，我需要知道如何。
快速谷歌搜索 - webcheatsheet.com/php/send_email_text_html_attachment.php
@ChristianNikkanen 这只是一个设置好的脚本，它还有很多难以完成的功能。为什么要重新发明***？它不使用任何额外的插件。
【参考方案1】：
要发送带附件的电子邮件，我们需要使用 multipart/mixed MIME 类型，指定混合类型将包含在电子邮件中。此外，我们希望使用 multipart/alternative MIME 类型来发送纯文本和 HTML 版本的电子邮件。请看示例：
<?php
//define the receiver of the email
$to = 'youraddress@example.com';
//define the subject of the email
$subject = 'Test email with attachment';
//create a boundary string. It must be unique
//so we use the MD5 algorithm to generate a random hash
$random_hash = md5(date('r', time()));
//define the headers we want passed. Note that they are separated with \r\n
$headers = "From: webmaster@example.com\r\nReply-To: webmaster@example.com";
//add boundary string and mime type specification
$headers .= "\r\nContent-Type: multipart/mixed; boundary=\"PHP-mixed-".$random_hash."\"";
//read the atachment file contents into a string,
//encode it with MIME base64,
//and split it into smaller chunks
$attachment = chunk_split(base64_encode(file_get_contents('attachment.zip')));
//define the body of the message.
ob_start(); //Turn on output buffering
?>
--PHP-mixed-<?php echo $random_hash; ?>
Content-Type: multipart/alternative; boundary="PHP-alt-<?php echo $random_hash; ?>"
--PHP-alt-<?php echo $random_hash; ?>
Content-Type: text/plain; charset="iso-8859-1"
Content-Transfer-Encoding: 7bit
Hello World!!!
This is simple text email message.
--PHP-alt-<?php echo $random_hash; ?>
Content-Type: text/html; charset="iso-8859-1"
Content-Transfer-Encoding: 7bit
<h2>Hello World!</h2>
<p>This is something with <b>HTML</b> formatting.</p>
--PHP-alt-<?php echo $random_hash; ?>--
--PHP-mixed-<?php echo $random_hash; ?>
Content-Type: application/zip; name="attachment.zip"
Content-Transfer-Encoding: base64
Content-Disposition: attachment
<?php echo $attachment; ?>
--PHP-mixed-<?php echo $random_hash; ?>--
<?php
//copy current buffer contents into $message variable and delete current output buffer
$message = ob_get_clean();
//send the email
$mail_sent = @mail( $to, $subject, $message, $headers );
//if the message is sent successfully print "Mail sent". Otherwise print "Mail failed"
echo $mail_sent ? "Mail sent" : "Mail failed";
?>
如您所见，发送带有附件的电子邮件很容易完成。在前面的示例中，我们有 multipart/mixed MIME 类型，在其中我们有 multipart/alternative MIME 类型，它指定了电子邮件的两个版本。为了在我们的消息中包含附件，我们将指定文件中的数据读入字符串，使用 base64 对其进行编码，将其拆分为更小的块以确保它符合 MIME 规范，然后将其作为附件包含。

复制/粘贴我在 OP cmets 中添加的链接中的内容 良好的 sn-p，尽管我必须在边界字符串之后提供一个额外的换行符才能使其工作。我猜它与php文件的行尾有关。我的编辑器默认使用 LF，但我认为标准也需要回车 (CRLF)。【参考方案2】：我同意 cmets 中的@MihaiIorga - 使用 PHPMailer 脚本。你听起来像是在拒绝它，因为你想要更简单的选择。相信我，与尝试使用 PHP 的内置 mail() 函数自己做相比，PHPMailer 是更容易的选择。 PHP 的mail() 函数确实不是很好。
使用 PHPMailer：
从这里下载 PHPMailer 脚本：http://github.com/PHPMailer/PHPMailer 解压存档并将脚本文件夹复制到项目中方便的位置。 包含主脚本文件 --require_once('path/to/file/class.phpmailer.php');
现在，发送带有附件的电子邮件变得异常简单：
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;
$email = new PHPMailer();
$email->SetFrom('you@example.com', 'Your Name'); //Name is optional
$email->Subject = 'Message Subject';
$email->Body = $bodytext;
$email->AddAddress( 'destinationaddress@example.com' );
$file_to_attach = 'PATH_OF_YOUR_FILE_HERE';
$email->AddAttachment( $file_to_attach , 'NameOfFile.pdf' );
return $email->Send();
就这么一行$email->AddAttachment();——你再简单不过了。
如果您使用 PHP 的 mail() 函数来做这件事，您将编写大量代码，并且您可能会遇到很多非常难以发现的错误。
【讨论】：
我也一样——想使用 mail() 只是因为我的代码中已经有了它。 PHPMAILER 花了我不到 5 分钟的时间来获取发送附件！ PHPMAILER 对许多人来说似乎是一个不错的简单方法。但是使用它需要不必要地导入另一个值得信任的东西（即 PHPMailer 中没有错误/等）。为了不盲目相信，需要查看至少 3155 行 sloc (115.456 kb) 的代码。鉴于替代纯 mail() 使用答案，这似乎是一个更糟糕的权衡。替代答案可以使用不到 100 sloc。不喜欢“我想要 A”的答案是“不，使用 B 更好”。其他答案告诉“A 是这样完成的”。 我发现这个问题正在寻找如何使用mail() 函数添加附件的答案。这个答案对我没有帮助。
这不是问题的答案。如何使用 PHPMailer 发送附件不是如何使用 PHP 的 mail() 发送附件，这是所要求的。
这个答案也忽略了项目使用的许可证。通过使用 PHPMailer，您必须确保从源代码中排除该软件包，以防止其 LGPL 许可证出现问题。【参考方案3】：
您可以尝试使用以下代码：
$filename = 'myfile';
$path = 'your path goes here';
$file = $path . "/" . $filename;
$mailto = 'mail@mail.com';
$subject = 'Subject';
$message = 'My message';
$content = file_get_contents($file);
$content = chunk_split(base64_encode($content));
// a random hash will be necessary to send mixed content
$separator = md5(time());
// carriage return type (RFC)
$eol = "\r\n";
// main header (multipart mandatory)
$headers = "From: name <test@test.com>" . $eol;
$headers .= "MIME-Version: 1.0" . $eol;
$headers .= "Content-Type: multipart/mixed; boundary=\"" . $separator . "\"" . $eol;
$headers .= "Content-Transfer-Encoding: 7bit" . $eol;
$headers .= "This is a MIME encoded message." . $eol;
// message
$body = "--" . $separator . $eol;
$body .= "Content-Type: text/plain; charset=\"iso-8859-1\"" . $eol;
$body .= "Content-Transfer-Encoding: 8bit" . $eol;
$body .= $message . $eol;
// attachment
$body .= "--" . $separator . $eol;
$body .= "Content-Type: application/octet-stream; name=\"" . $filename . "\"" . $eol;
$body .= "Content-Transfer-Encoding: base64" . $eol;
$body .= "Content-Disposition: attachment" . $eol;
$body .= $content . $eol;
$body .= "--" . $separator . "--";
//SEND Mail
if (mail($mailto, $subject, $body, $headers))
echo "mail send ... OK"; // or use booleans here
else
echo "mail send ... ERROR!";
print_r( error_get_last() );
2018 年 6 月 14 日编辑
为了提高某些电子邮件提供商的可读性 使用
$body .= $eol . $message . $eol . $eol; 和
$body .= $eol . $content . $eol . $eol;
【讨论】：
$uid 似乎没有使用。 有人在an answer that should be a comment中指出，既然OP的代码是'Example message with <b>html</b>'，那么Content-Type应该是text/html而不是text/plain。我代表他发布评论，因为他没有足够的代表来发布 cmets，我已将答案标记为删除。
在这段代码中，你必须定义$path和$filename吗？它会像 $filename = $_FILES['userfile']['tmp_name']; ?
来自 PHPMailer 的文档... “正确格式化电子邮件非常困难。有无数重叠的 RFC，需要严格遵守极其复杂的格式化和编码规则 - 您可以在网上找到绝大多数代码直接使用 mail() 函数是完全错误的！” ...这是真的！我已经使用类似这个答案的东西来发送带有附件的邮件并且它有效！几天后才发现，虽然 Gmail 显示附件很好，但其他提供商直接在邮件中显示 base64 内容。
正文丢失，只发送附件【参考方案4】：
Swiftmailer 是另一个易于使用的脚本，可自动防御email injection 并使附件变得轻而易举。我也强烈反对使用 PHP 的内置 mail() 函数。
使用方法：
下载Swiftmailer，并将lib文件夹放入您的项目中
使用require_once 'lib/swift_required.php'; 包含主文件
现在在需要邮寄的时候添加代码：
// Create the message
$message = Swift_Message::newInstance()
->setSubject('Your subject')
->setFrom(array('webmaster@mysite.com' => 'Web Master'))
->setTo(array('receiver@example.com'))
->setBody('Here is the message itself')
->attach(Swift_Attachment::fromPath('myPDF.pdf'));
//send the message
$mailer->send($message);
更多信息和选项可以在Swiftmailer Docs找到。
【讨论】：
因为你提供 dwonload 第三方库，我猜 PHPMailer 不是 3rd-party 吗？或者是说@MatthewJohnson 是 swiftmailer 的维护者还是其中的一部分？无论哪种方式，只要解决方案是好的和有效的，投反对票都是不合适的...... @Xsmael，PHPMailer 绝对是第 3 方 :) 我不同意反对意见，因为（至少在当时）该解决方案确实有效。然而，人们可以随心所欲地投票，而且赞成票超过了反对票。【参考方案5】：工作理念：

【讨论】：
@Jon。 $filename, 是文件的实际名称，$path 是没有文件名的实际文件路径。我认为这些变量的描述性足以声明和建立它们 发送多个附件的注意事项 - 使用$nmessage .= "--".$uid."\r\n"; 分隔 MIME 部分，在最后的 MIME 部分之后，使用 $nmessage .= "--".$uid."--";（如上所示）。
在尝试让愚蠢的 phpmailer 工作感到头疼之后，这终于奏效了。
这个确实有效。接受的答案对我不起作用。它会发送损坏的文件。
这是一个非常清晰和干净的答案。它在 Outlook、Gmail 等接收时有效。整洁的答案。如果你可以用 HTML 消息部分更新，这将变得更加完整。【参考方案7】：

由于用户输入缺乏验证和适当的上下文转义，此代码容易受到标头注入攻击。 @Synchro ..这是我为多个附件找到的唯一对我有用的代码..您能否建议如何以安全的方式使用它。【参考方案12】： $to = "to@gmail.com";
$subject = "Subject Of The Mail";

【参考方案13】：由于指定的附件格式 (application/octet-stream)，以上答案均不适合我。使用 application/pdf 以获得 PDF 文件的最佳效果。
<?php
// just edit these
$to = "email1@domain.com, email2@domain.com"; // addresses to email pdf to
$from = "sent_from@domain.com"; // address message is sent from
$subject = "Your PDF email subject"; // email subject
$body = "<p>The PDF is attached.</p>"; // email body
$pdfLocation = "./your-pdf.pdf"; // file location
$pdfName = "pdf-file.pdf"; // pdf file name recipient will get
$filetype = "application/pdf"; // type
// creates headers and mime boundary
$eol = PHP_EOL;
$semi_rand = md5(time());
$mime_boundary = "==Multipart_Boundary_$semi_rand";
$headers = "From: $from$eolMIME-Version: 1.0$eol" .
"Content-Type: multipart/mixed;$eol boundary=\"$mime_boundary\"";
// add html message body
$message = "--$mime_boundary$eol" .
"Content-Type: text/html; charset=\"iso-8859-1\"$eol" .
"Content-Transfer-Encoding: 7bit$eol$eol$body$eol";
// fetches pdf
$file = fopen($pdfLocation, 'rb');
$data = fread($file, filesize($pdfLocation));
fclose($file);
$pdf = chunk_split(base64_encode($data));
// attaches pdf to email
$message .= "--$mime_boundary$eol" .
"Content-Type: $filetype;$eol name=\"$pdfName\"$eol" .
"Content-Disposition: attachment;$eol filename=\"$pdfName\"$eol" .
"Content-Transfer-Encoding: base64$eol$eol$pdf$eol--$mime_boundary--";
// Sends the email
if(mail($to, $subject, $message, $headers))
echo "The email was sent.";
else
echo "There was an error sending the mail.";
【讨论】：
$headers = "From: $from$eolMIME-Version: 1.0$eol" 在 $eolMIME 上不断抛出未定义变量错误。 嗯...替换"From: $from$eolMIME-Version: 1.0$eol" 为 "From: $from" . "$eolMIME-Version: 1.0$eol"
也许它不会让你像在某些版本的 php 中那样添加两个变量，它适用于我正在使用的那个。对于那个很抱歉。事实上，您可能想用" . "$eol 替换所有$eol 实例，这样一来就完成了。【参考方案14】：
