推荐答案

您需要设置正确的邮件标题，然后通过将文件编码为您在标题中声明的任何格式来附加文件，例如以下代码段:

You need to set the right mail-headers, and then attach the file by encoding it to whatever form you have declared in the header, like in this snippet:

您在这里需要做的就是读取文件并对其进行编码(在这种情况下，编码为base64)

All you need to do here, is read the file, and encode it (to base64 in this case)

$file = fopen($fileatt,'rb');
$data = fread($file,filesize($fileatt));
fclose($file);

$data = chunk_split(base64_encode($data)); 

首先，您需要一个边界，就像一条规则来告诉一个零件在哪里停止，而另一零件在哪里开始

first you'll need a boundary, like a rule to tell where one part stops, and the other begins

$semi_rand = md5(time());
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";

然后将标题设置为正确，以支持附件

then set the headers right, to support attachement

$headers .= "\nMIME-Version: 1.0\n" .
"Content-Type: multipart/mixed;\n" .
" boundary=\"{$mime_boundary}\"";

然后建立您的消息

$email_message .= "This is a multi-part message in MIME format.\n\n" .
"--{$mime_boundary}\n" . // start text block
"Content-Type:text/html; charset=\"iso-8859-1\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" .
$email_content . "\n\n" .
"--{$mime_boundary}\n" . // start attachement
"Content-Type: {$fileatt_type};\n" .
" name=\"{$fileatt_name}\"\n" .
//"Content-Disposition: attachment;\n" .
//" filename=\"{$fileatt_name}\"\n" .
"Content-Transfer-Encoding: base64\n\n" .
$data . "\n\n" . // this is the file...
"--{$mime_boundary}\n";  

然后...使用邮件;-)

and then... sent the message using mail ;-)

mail($email_to, $email_subject, $email_message, $headers)
