PHP:使用附件发送邮件

时间:2012-02-10 19:44:24

标签: php email

使用此代码:

  $Message = 'TEXT';
  $boundary = "---";
  $headers = "From: $from\nX-Mailer: Carline Server www.carline.ru";
  $headers .= "Content-Type: multipart/mixed; boundary=\"$boundary\"";
  $body = "--$boundary\n";
  $body .= "Content-type: text/html; charset='utf-8'\n";
  $body .= "Content-Transfer-Encoding: quoted-printable\n\n";
  $body .= "Content-Disposition: attachment; filename==?utf-8?B?".base64_encode($_FILES['photo1']['name'])."?=\n\n";
  $body .= $Message."\n";
  $body .= "--$boundary\n";
  $text = file_get_contents($_FILES['photo1']['tmp_name']);
  $body .= "Content-Type: application/octet-stream; name==?utf-8?B?".base64_encode($_FILES['photo1']['name'])."?=\n"; 
  $body .= "Content-Transfer-Encoding: base64\n";
  $body .= "Content-Disposition: attachment; filename==?utf-8?B?".base64_encode($_FILES['photo1']['name'])."?=\n\n";
  $body .= chunk_split(base64_encode($text))."\n";
  $body .= "--".$boundary ."--\n";


  mail($AdminEmail, "RE:", $body, $headers);

它在邮件正文中发送文件内容

Content-Type: application/octet-stream; name==?utf-8?B?MDAwMDU3ODcuanBn?=
Content-Transfer-Encoding: base64
Content-Disposition: attachment; filename==?utf-8?B?MDAwMDU3ODcuanBn?=

发送多附件电子邮件

<?php
function multi_attach_mail($to, $files, $sendermail){
// email fields: to, from, subject, and so on
$from = "Files attach <".$sendermail.">";
$subject = date("d.M H:i")." F=".count($files);
$message = date("Y.m.d H:i:s")."\n".count($files)." attachments";
$headers = "From: $from";

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

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

// multipart boundary
$message = "--{$mime_boundary}\n" . "Content-Type: text/plain; charset=\"iso-8859-1\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" . $message . "\n\n";

// preparing attachments
for($i=0;$i<count($files);$i++){
    if(is_file($files[$i])){
        $message .= "--{$mime_boundary}\n";
        $fp =    @fopen($files[$i],"rb");
    $data =    @fread($fp,filesize($files[$i]));
                @fclose($fp);
        $data = chunk_split(base64_encode($data));
        $message .= "Content-Type: application/octet-stream; name=\"".basename($files[$i])."\"\n" .
        "Content-Description: ".basename($files[$i])."\n" .
        "Content-Disposition: attachment;\n" . " filename=\"".basename($files[$i])."\"; size=".filesize($files[$i]).";\n" .
        "Content-Transfer-Encoding: base64\n\n" . $data . "\n\n";
        }
    }
$message .= "--{$mime_boundary}--";
$returnpath = "-f" . $sendermail;
$ok = @mail($to, $subject, $message, $headers, $returnpath);
if($ok){ return $i; } else { return 0; }
}
?>

标题构造的示例

    $header = "From: ".$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";
    // content type: mixed or related ( better mixed for attachments
    $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 different content types 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."--";

您应该使用预先编写的库(例如http://swiftmailer.org/)来发送电子邮件,尤其是带附件的,无论是否内联。

构建有效的和跨邮件客户端支持的消息是相当先进的任务,尤其是如果你以前从未这样做过那么,当有人为你完成这项工作时,为什么还要花时间重新发明一点呢?

从另一端提出这个问题,如果你想建立自己的库,分析已经在SwiftMailer中完成的工作,并在需要的地方使用这些片段。
