使用IMAP和PHP保存附件服务器 [英] Save Attachments Server with IMAP and PHP

问题描述

现在，我正在使用此代码从服务器中获取电子邮件.

Right now I am using this code to fetch emails from my server.

<?php
$imap = imap_open($server, $username, $password) or die("Connection Error");
$message_count = imap_num_msg($imap);
for ($i = 1; $i <= $message_count; ++$i){

    $header = imap_header($imap, $i);
    //print_r($header);

    $email[$i]['fromaddress'] = $header->from[0]->personal;
    $email[$i]['to'] = $header->to[0]->mailbox;
    $email[$i]['subject'] = $header->subject;
    $email[$i]['message_id'] = $header->message_id;
    $email[$i]['date'] = $header->udate;

    $from = $email[$i]['fromaddress'];
    $from_email = $email[$i]['from'];
    $to = $email[$i]['to'];
    $subject = $email[$i]['subject'];

    echo $from_email . '</br>';
    echo $to . '</br>';
    echo $subject . '</br>';

    imap_setflag_full($imap, $i, "\\Seen");
    imap_mail_move($imap, $i, 'Trash');
}

imap_close($imap);

?>

我也希望能够提取附件并将​​其保存到服务器上的文件夹中，并在输出中显示这些附件的链接.最简单的方法是什么?

I would like to be able to take the attachments as well and save them to a folder on my server and display a link to those attachments in the output. What is the simplest way to accomplish this?

推荐答案

实际上，我可以通过以下操作使它完全实现我想要的功能:

I actually was able to get it to do exactly what I wanted with the following:

<?php

function getFileExtension($fileName){
   $parts=explode(".",$fileName);
   return $parts[count($parts)-1];
}

$imap = imap_open($server, $username, $password) or die("imap connection error");
$message_count = imap_num_msg($imap);
for ($m = 1; $m <= $message_count; ++$m){

    $header = imap_header($imap, $m);
    //print_r($header);

    $email[$m]['from'] = $header->from[0]->mailbox.'@'.$header->from[0]->host;
    $email[$m]['fromaddress'] = $header->from[0]->personal;
    $email[$m]['to'] = $header->to[0]->mailbox;
    $email[$m]['subject'] = $header->subject;
    $email[$m]['message_id'] = $header->message_id;
    $email[$m]['date'] = $header->udate;

    $from = $email[$m]['fromaddress'];
    $from_email = $email[$m]['from'];
    $to = $email[$m]['to'];
    $subject = $email[$m]['subject'];

    echo $from_email . '</br>';
    echo $to . '</br>';
    echo $subject . '</br>';

    $structure = imap_fetchstructure($imap, $m);

    $attachments = array();
    if(isset($structure->parts) && count($structure->parts)) {

        for($i = 0; $i < count($structure->parts); $i++) {

            $attachments[$i] = array(
                'is_attachment' => false,
                'filename' => '',
                'name' => '',
                'attachment' => ''
            );

            if($structure->parts[$i]->ifdparameters) {
                foreach($structure->parts[$i]->dparameters as $object) {
                    if(strtolower($object->attribute) == 'filename') {
                        $attachments[$i]['is_attachment'] = true;
                        $attachments[$i]['filename'] = $object->value;
                    }
                }
            }

            if($structure->parts[$i]->ifparameters) {
                foreach($structure->parts[$i]->parameters as $object) {
                    if(strtolower($object->attribute) == 'name') {
                        $attachments[$i]['is_attachment'] = true;
                        $attachments[$i]['name'] = $object->value;
                    }
                }
            }

            if($attachments[$i]['is_attachment']) {
                $attachments[$i]['attachment'] = imap_fetchbody($imap, $m, $i+1);
                if($structure->parts[$i]->encoding == 3) { // 3 = BASE64
                    $attachments[$i]['attachment'] = base64_decode($attachments[$i]['attachment']);
                }
                elseif($structure->parts[$i]->encoding == 4) { // 4 = QUOTED-PRINTABLE
                    $attachments[$i]['attachment'] = quoted_printable_decode($attachments[$i]['attachment']);
                }
            }
        }
    }

    foreach ($attachments as $key => $attachment) {
        $name = $attachment['name'];
        $contents = $attachment['attachment'];
        file_put_contents($name, $contents);
    }

    //imap_setflag_full($imap, $i, "\\Seen");
    //imap_mail_move($imap, $i, 'Trash');
}

imap_close($imap);

?>
