PHP - 邮件不会发送附件，只有没有它附件
问题描述：
矿山脚本不会发送附件（这是为更多的人，但单一给出同样的问题）。PHP - 邮件不会发送附件，只有没有它附件
有代码：
if ($_POST) {
$to = mysql_real_escape_string($_POST['to']);
$subject = mysql_real_escape_string($_POST['subject']);
$message = mysql_real_escape_string($_POST['message']);
if (empty($to) || empty($subject) || empty($message)) {
header("location: nation.php?error=empty");
} else {
$email = $b['email'];
$my_file = $_FILES['my_file']['tmp_name'];
$my_file_type = $_FILES['my_file']['type'];
$my_file_name = $_FILES['my_file']['name'];
$body = "";
//upload
if (is_uploaded_file($my_file))
{
$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= 'From: <'.$email.'>' . "\r\n";
$headers .= "Content-Type: multipart/mixed;\n";
// Apro e leggo il file my_file
$file = fopen($my_file,'rb');
$data = fread($file, filesize($my_file));
fclose($file);
// Adatto il file al formato MIME base64 usando base64_encode
$data = chunk_split(base64_encode($data));
// Genero il "separatore"
// Serve per dividere, appunto, le varie parti del messaggio.
// Nel nostro caso separerà la parte testuale dall'my_file
$semi_rand = md5(time());
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";
// Aggiungo le intestazioni necessarie per l'my_file
$headers .= "Content-Type: multipart/mixed;\n";
$headers .= " boundary=\"{$mime_boundary}\"";
// Definisco il tipo di messaggio (MIME/multi-part)
$body .= "This is a multi-part message in MIME format.\n\n";
// Metto il separatore
$body .= "--{$mime_boundary}\n";
// Questa è la parte "testuale" del messaggio
$body .= "Content-Type: text/plain; charset=\"iso-8859-1\"\n";
$body .= "Content-Transfer-Encoding: 7bit\n\n";
$body .= $message . "\n\n";
// Metto il separatore
$body .= "--{$mime_boundary}\n";
// Aggiungo l'my_file al messaggio
$body .= "Content-Disposition: attachment; filename=\"{$my_file_name}\"\n";
$body .= "Content-Transfer-Encoding: base64\n\n";
$body .= $data . "\n\n";
// chiudo con il separatore
$body .= "--{$mime_boundary}--\n";

}
} else {
$name = 'error';
}
} else {

}
就职于5/6分钟......对不起，糟糕的代码，我'不是专家：\ 它发送电子邮件没有依附，我好困惑，问题在哪里？
答
如果您想发送带有附件的邮件，您可能需要查看一些外部库，例如PHPMailer。在那里你可以添加一个简单的附件$ mail-> addAtachment（'path/To/File.extension'）。
使用mail（）函数发送电子邮件时，邮件最终会出现在垃圾邮件文件夹中的可能性很大。 使用PHPmailer，您可以使用SMTP验证和可信的SMTP服务器，这将减少您的邮件被视为垃圾邮件的几率。
