KimNyholm 发布了一组 imap 客户端方法，其中包含您所要求的目标：https://github.com/KimNyholm/ubuntu-web-development/blob/master/php/imapClient.php https://github.com/KimNyholm/ubuntu-web-development/blob/master/php/imapClient.php
他编写这段代码是因为缺乏处理 php imap 消息的完整教程和代码示例，正如他在此处解释的那样：http://kimnyholm.com/a-simple-imap-mail-reader-client/ http://kimnyholm.com/a-simple-imap-mail-reader-client/并将他的一些代码基于 drupal 库。
我附上执行您提到的步骤的方法的摘录，我希望它能解决问题，尽管我发现它并不是最近的：
检查其中的附件和图像：
// ATTACHMENT
// Any part with a filename is an attachment,
// so an attached text file (type 0) is not mistaken as the message.
if(isset($parameter['filename']) || isset($parameter['name'])) {
$filename = ($parameter['filename'])? $parameter['filename'] : $parameter['name'];
$filename=iconv_mime_decode($filename, ICONV_MIME_DECODE_CONTINUE_ON_ERROR, 'UTF-8');
$id = isset($part->id) ? $part->id : '' ;
$attachments[] = array('inline' => false, 'filename' => $filename, 'part' => $partNo, 'data' => $data, 'id' => $id);
}
if ($type==TYPEIMAGE){
$info=fetchImageInfo($mailbox, $emailNumber, $partNo);
$attachments[] = array('inline' => true, 'filename' => $info['filename'], 'part' => $partNo, 'data' => $data, 'id' => $info['id']);
}
在这里，他将数据保存到临时目录并下载：
function EmailAttachmentsSave(&$mail){
$html = '';
$attachments=$mail->attachments;
$msgNo=trim($mail->headerInfo->Msgno);
foreach ($attachments as $attachment) {
$partNo=$attachment['part'];
$tmpDir= "imapClient/$msgNo/$partNo";
$dirExists= is_dir($tmpDir);
if (!$dirExists){
$dirExists= mkdir($tmpDir, 0777, true) ;
}
$fileName=$attachment['filename'];
$tmpName = "$tmpDir/$fileName";
$saved = $dirExists && file_put_contents($tmpName, $attachment['data']);
$tmpName=htmlentities($tmpName);
$fileName=htmlentities($fileName);
if (!$attachment['inline']){
$html .= '<span><a href="' . $tmpName . '">' . $fileName . '</a> </span>';
}
$cid =$attachment['id'];
if (isset($cid)){
$mail->htmlText=EmailEmbeddedLinkReplace($mail->htmlText,$cid,$tmpName);
}
}
return $html ;
}
function EmailPrint($mail){
$headerInfo=$mail->headerInfo;
$html = '<h4>' . htmlentities($headerInfo->subject) . '</h4>';
$html .= '<p>From: ' . htmlentities($headerInfo->fromaddress) . '</p>';
$html .= '<p>To: ' . htmlentities($headerInfo->toaddress) . '</p>';
$html .= '<div style="background: lightgrey">' . (empty($mail->htmlText) ? ('<p>' . $mail->plainText . '</p>') : $mail->htmlText) . '</div>';
return $html ;
}
function EmailDownload($host, $user, $password){
$html = '<head> <meta charset="UTF-8"> </head>';
$html .= '<h3>Simple imap client</h3>';
$mails=EmailGetMany($host, $user, $password);
$count=count($mails);
$html .= "<p>$user has $count mails at $host.</p>";
foreach ($mails as $mail){
$html .= '<hr>';
$html .= EmailAttachmentsSave($mail);
$html .= EmailPrint($mail);
}
return $html ;
}
