发送附件与PHP邮件()?

我需要随邮件发送一份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?

要发送带有附件的电子邮件，我们需要使用multipart/mixed MIME类型，该类型指定混合类型将包含在电子邮件中。此外，我们希望使用多部分/替代MIME类型来发送纯文本和HTML版本的电子邮件。看一下这个例子:

<?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";
?>

正如你所看到的，发送带有附件的电子邮件很容易完成。在前面的例子中，我们有多部分/混合MIME类型，在里面我们有多部分/替代MIME类型，指定两个版本的电子邮件。为了将附件包含到消息中，我们将指定文件中的数据读入一个字符串，使用base64对其进行编码，将其分割为更小的块，以确保它与MIME规范匹配，然后将其作为附件包含。

最佳答案

我同意评论中的@MihaiIorga -使用PHPMailer脚本。听起来你拒绝是因为你想要更简单的选择。相信我，比起自己用PHP内置的mail()函数，PHPMailer 是是一个更简单的选择。PHP的mail()函数真的不是很好。

使用PHPMailer:

  • 从这里下载PHPMailer脚本:http://github.com/PHPMailer/PHPMailer
  • 提取归档文件并将脚本文件夹复制到项目中方便的位置。
  • 包括主脚本文件——require_once('path/to/file/class.phpmailer.php');

现在，发送带有附件的电子邮件从异常困难变得异常简单:

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();

它只是一行$email->AddAttachment();——你不能要求任何更容易。

如果你用PHP的mail()函数来做，你将会写一大堆代码，而且你可能会有很多很难找到的bug。

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() );
}

为更多的可读性在一些电子邮件提供商 使用< / p > < p > $body .= $eol . $message . $eol . $eol;和 $body .= $eol . $content . $eol . $eol; < / p >

Swiftmailer是另一个易于使用的脚本，它可以自动保护电子邮件注入，并使附件变得轻而易举。我也强烈反对使用PHP内置的mail()函数。

使用方法:

  • 下载Swiftmailer，并将lib文件夹放在你的项目中
  • 使用require_once 'lib/swift_required.php';包含主文件

现在当你需要邮寄时添加代码:

// 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文档中找到。

他首先创建了一个可以稍后调用的mail_attachment函数。他稍后用他的附件代码来做。

在与格式糟糕的附件斗争了一段时间后，我使用了以下代码:

$email = new PHPMailer();
$email->From      = 'from@somedomain.com';
$email->FromName  = 'FromName';
$email->Subject   = 'Subject';
$email->Body      = 'Body';
$email->AddAddress( 'to@somedomain.com' );
$email->AddAttachment( "/path/to/filename.ext" , "filename.ext", 'base64', 'application/octet-stream' );

$mail = new PHPMailer;
$mail->IsSMTP(); // telling the class to use SMTP
$mail->Host = "mail.companyname.com"; // SMTP server
$mail->SMTPDebug = 0;
$mail->SMTPAuth = true;
$mail->SMTPSecure = "ssl";
$mail->Host = "smtp.gmail.com";
$mail->Port = 465;
$mail->IsHTML(true);
$mail->Username = "info@companyname.com";  // GMAIL username
$mail->Password = "mailPassword";          // GMAIL password


$mail->SetFrom('info@companyname.com', 'new application submitted');
$mail->AddReplyTo("name@yourdomain.com","First Last");
$mail->Subject = "your subject";


$mail->AltBody = "To view the message, please use an HTML compatible email viewer!"; // optional, comment out and test


$mail->MsgHTML($email_message);


$address = 'info@companyname.com';
$mail->AddAddress($address, "companyname");


$mail->AddAttachment($_FILES['file']['tmp_name'], $_FILES['file']['name']);      // attachment


if (!$mail->Send()) {

我最终编写了自己的电子邮件发送/编码函数。这在我发送PDF附件时效果很好。我还没有在生产中使用其他特性。

注意:尽管规范非常强调必须使用\r\n来分隔头文件，但我发现它只在使用PHP_EOL时有效。我只在Linux上测试过这个功能。YMMV

上面的答案都不适合我，因为他们指定的附件格式(application/octet-stream)。使用application/pdf可获得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--";

你可以使用我创建的这个类发送常规邮件或附件邮件。
