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?

你可以使用我创建的这个类发送常规邮件或附件邮件。

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。

从这里拍的。

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' );
$email->Send();

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,比起自己使用PHP内置的mail()函数,PHPMailer是一个更简单的选择。PHP的mail()函数真的不是很好。

使用PHPMailer:

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();

只有一行$email-> addatattachment ();——再简单不过了。

如果使用PHP的mail()函数,则需要编写大量代码,并且可能会遇到许多很难找到的错误。

由于它们指定的附件格式(application/octet-stream),上面的答案都不适合我。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--";

// Sends the email
if(mail($to, $subject, $message, $headers)) {
    echo "The email was sent.";
}
else {
    echo "There was an error sending the mail.";
}
