How to save image attachment from email using IMAP & PHP?
I've successfully written script that connects to my mail server and retrieves 开发者_如何转开发the headers and bodies of all new messages. I want to take it one step further to detect if attachment exists (images only), if so, download to server.
How to go about this using PHP & IMAP?
Thanks in advance
KimNyholm published an imap client set of methods that enclose the goals you ask: https://github.com/KimNyholm/ubuntu-web-development/blob/master/php/imapClient.php
He wrote this code because of the lack of full tutorials and code examples to process php imap messages, as he explains here: http://kimnyholm.com/a-simple-imap-mail-reader-client/ and based some of his code in drupal libraries.
I enclose an extract of the methods that perform the steps you menction, I hope it solves the question even though I see it's not exactly recent:
Check for attachments and images amongst them:
// 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' => $info['id']);
}
Here he saves the data to a tempdir and download it:
function EmailAttachmentsSave(&$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 ;
}
