Question

任何人都可以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？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>"; 
}
?>

但此代码不附加来自服务器的文件。请帮帮我..提前谢谢.. !!

一个问题：您是否希望发送带附件的电子邮件，或者您是否希望通过此问题提高您的PHP技能？

如果您只想发送邮件，请查看PHPMailer，这是非常好并且易于处理。对我自己而言，我已经使用了多年没有问题。

为了提高你的技能：你说附件是用base64编码的，但我找不到像 $ data = base64_encode（$ data）; 这样的行你添加 $ data 您的附件明确邮寄。
