将服务器中的文件附加到电子邮件中

Question

有人能告诉我如何从服务器附加文件并通过电子邮件将其作为附件发送吗？？我有以下代码：

<?php 
// Read POST request params into global vars 
$to      = $_POST['to'];
$from    = $_POST['from'];
$subject = $_POST['subject']; 
$message = $_POST['message'];
// Obtain file upload vars
$fileatt      = $_FILES['fileatt']['tmp_name']; 
$fileatt_type = $_FILES['fileatt']['type'];
$fileatt_name = $_FILES['fileatt']['name'];
$headers = "From: $from";  
if (is_uploaded_file($fileatt)) {
// Read the file to be attached ('rb' = read binary)
$file = fopen($fileatt,'rb'); 
$data = fread($file,filesize($fileatt)); 
fclose($file);
// Generate a boundary string 
$semi_rand = md5(time());
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";
// Add the headers for a file attachment  
$headers .= "nMIME-Version: 1.0n" .
        "Content-Type: multipart/mixed;n" . 
        " boundary="{$mime_boundary}""; 
// Add a multipart boundary above the plain message 
 $message = "This is a multi-part message in MIME format.nn" . 
"--{$mime_boundary}n" .
"Content-Type: text/plain; charset="iso-8859-1"n" . 
"Content-Transfer-Encoding: 7bitnn" .   
$message . "nn"; 
// Base64 encode the file data 
// Add file attachment to the message 
$message .= "--{$mime_boundary}n" .
"Content-Type: {$fileatt_type};n" .
 " name="{$fileatt_name}"n" . 
//"Content-Disposition: attachment;n" . 
//" filename="{$fileatt_name}"n" .
"Content-Transfer-Encoding: base64nn" .              
          $data . "nn" .  "--{$mime_boundary}--n"; 
}
// Send the message 
$ok = @mail($to, $subject, $message, $headers); 
if ($ok) { 
echo "<p>Mail sent! Yay PHP!</p>"; 
} else { 
echo "<p>Mail could not be sent. Sorry!</p>"; 
}
?>

但此代码不会附加来自服务器的文件。请帮帮我。。提前感谢。。！！

有一个问题：你想用附件发送电子邮件，还是想通过这个问题提高你的PHP技能？

如果你只想发送邮件，可以看看PHPMailer，它非常好，很容易处理。对我自己来说，我多年来一直在使用这个，没有任何问题。

为了提高你的技能：你说附件是用base64编码的，但我找不到你做类似$data=base64_encode（$data）的事情的那一行您将附件的$data以明文形式添加到邮件中。
