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?

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.";
}

这对我很有用。它还附加了多个附件。很容易

$attachments = $_FILES['file'];
//php validation
if (strlen($sender_name) < 4) {
die('Name is too short or empty');
}
if (!filter_var($sender_email, FILTER_VALIDATE_EMAIL)) {

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。
