我知道有很多与 PHP 邮件功能相关的帖子。但说真的，我无法弄清楚下面的代码有什么问题：
$subject = "New article submitted.";
$message = "You've received this e-mail through your website's write an article form: \n";
$message .= "Name: {$data['username']} \n";
$message .= "E-mail: {$data['email']} \n";
$message .= "\nRegards,\nAakriti \n";
$headers = "From: {$data['name']} <{$data['email']}> \n";
// Boundary
$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;\n charset=\"iso-8859-1\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" .
$message . "\n\n" .
"--{$mime_boundary}\n";
// preparing attachments
for($i=0;$i < count($_FILES['articledata']['name']); $i++) {
// store the file information to variables for easier access
$tmp_name = $_FILES['articledata']['tmp_name'][$i];
$type = $_FILES['articledata']['type'][$i];
$name = $_FILES['articledata']['name'][$i];
$size = $_FILES['articledata']['size'][$i];
$file = fopen($tmp_name,"rb");
$attachment = fread($file,filesize($tmp_name));
fclose($file);
$attachment = chunk_split(base64_encode($attachment));
print_r($attachment);
//$attachment = chunk_split(base64_encode(file_get_contents($tmp_name)));
$message .= "Content-Type: {$type};\n" .
" name=\"{$name}\"\n" .
"Content-Transfer-Encoding: base64\n" .
"Content-Disposition: attachment;\n" .
" filename=\"{$name}\"\n\n" .
$attachment . "\n" .
"--{$mime_boundary}\n";
$message .= "--\n\n";
}
$headers .= "Reply-To: <{$data['email']}>";
if (mail($recipient,$subject,$message,$headers)) {
echo "<p>Thank you! Your mail was successfully sent to the webmaster. Thank you for your time.</p>";
} else {
echo "<p>Sorry, there was an error and your mail was not sent. Please find an alternative method of contacting the webmaster.</p>";
}
它只是没有按预期工作。附件是一些二进制文本。看看下面：
MIME-Version: 1.0
Content-Type: multipart/mixed;
boundary="==Multipart_Boundary_xf6a3dd3e1c0c1f9233b8c66ce2a73e3ex"Reply-To: <test03@gmail.com>
This is a multi-part message in MIME format.
--==Multipart_Boundary_xf6a3dd3e1c0c1f9233b8c66ce2a73e3ex
Content-Type: text/plain;
charset="iso-8859-1"
Content-Transfer-Encoding: 7bit
You've received this e-mail through your website's write an article form:
Name: Johnson
E-mail: test@gmail.com
Regards,

更新：在打破我的脑袋几个小时后终于把它修好了..有几个问题：
正如asachanfbd mime 边界所指出的那样，没有正确嵌套。
这是一个很愚蠢的问题，但它是罪魁祸首——在下面的代码行处有额外的换行符：
$message .= "\n问候，\nAakriti \n"; $headers = "来自：{$data['name']} <{$data['email']}> \n";
感谢大家！
