谁能给我一些想法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？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  
$headers .= "\nMIME-Version: 1.0\n" .
        "Content-Type: multipart/mixed;\n" . 
        " boundary=\"{$mime_boundary}\""; 
// Add a multipart boundary above the plain message 
 $message = "This is a multi-part message in MIME format.\n\n" . 
"--{$mime_boundary}\n" .
"Content-Type: text/plain; charset=\"iso-8859-1\"\n" . 
"Content-Transfer-Encoding: 7bit\n\n" .   
$message . "\n\n"; 
// 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: base64\n\n" .              
          $data . "\n\n" .  "--{$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>"; 
}
?>

但此代码不会从服务器附加文件。请帮帮我..提前谢谢..!!

一个问题：您想发送带有附件的电子邮件还是想通过这个问题提高您的 PHP 技能？

如果您只想发送邮件，请查看PHPMailer，它非常好且易于处理。对于我自己来说，我多年来一直在使用它，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);的那一行。您将附件的$data直接添加到邮件中。
