附加电子邮件在 php 5.2.11 中发送

Question

我在发送带有附件的电子邮件时遇到问题。

它可以在安装了 php 5.2.8 的服务器上运行，而不能在安装了 php 5.2.11 的其他服务器上运行。 下面是函数

function mail_attachment($filename, $path, $mailto, $from_mail, $from_name, $replyto, $subject, $message) 
{
    $file = $path.$filename;
    $file_size = filesize($file);
    $handle = fopen($file, "r");
    $content = fread($handle, $file_size);
    fclose($handle);
    $content = chunk_split(base64_encode($content));
    $uid = md5(uniqid(time()));
    $name = basename($file);
    $header = "From: ".$from_name." <".$from_mail.">\r\n";
    $header .= "Reply-To: ".$replyto."\r\n";
    $header .= "MIME-Version: 1.0\r\n";
    $header .= "Content-Type: multipart/mixed; boundary=\"".$uid."\"\r\n\r\n";
    $header .= "This is a multi-part message in MIME format.\r\n";
    $header .= "--".$uid."\r\n";
    $header .= "Content-type:text/plain; charset=iso-8859-1\r\n";
    $header .= "Content-Transfer-Encoding: 7bit\r\n\r\n";
    $header .= $message."\r\n\r\n";
    $header .= "--".$uid."\r\n";
    $header .= "Content-Type: application/octet-stream; name=\"".$filename."\"\r\n"; // use diff. tyoes here 
    $header .= "Content-Transfer-Encoding: base64\r\n";
    $header .= "Content-Disposition: attachment; filename=\"".$filename."\"\r\n\r\n";
    $header .= $content."\r\n\r\n";
    $header .= "--".$uid."--";
    if (mail($mailto, $subject, "", $header)) {
       echo  "Picture Uploaded Successfully... OK"; // or use booleans here
  return true;
    } else {
        echo  "mail send ... ERROR!";
return false;
    }
}

使用邮件库，例如 Swift Mailer 或 PHPMailer。
