PHP IMAP. Stop Messages Being Marked as Seen - php

Question

I'm retrieving Gmail e-mails through IMAP. I'm setting the FT_PEEK option wherever I can, and finally, I've even opened the mailbox as read-only (OP_READONLY). Yet, my code is marking the messages as read.
Here is the code:
class imap{
CONST HOSTNAME='{imap.gmail.com:993/imap/ssl}INBOX';
CONST USERNAME = '[Address hidden]';
CONST PASSWORD = '[Password hidden]'; //App password from Google
function getMessagesSince($date){
//This will return a collection of email objects.
$messages=array();
if(!$imap=imap_open($this::HOSTNAME, $this::USERNAME, $this::PASSWORD, OP_READONLY)) throw new exception("Unable to connect to IMAP mailbox. ".imap_last_error());
$since=date_format($date, 'j F Y');
$emails=imap_search($imap, 'SINCE "'.$since.'"', SE_UID|FT_PEEK);
foreach($emails as $email){
$messages[]=$this->getMessage($email, $imap);
}
imap_close($imap);
return $messages;
}
private function getMessage($uid, $imap){
//First get the headers
$headers=$this->getHeaders($uid, $imap);
$datereceived=date('Y-m-d H:i:s', strtotime($headers->date));
$sender=$headers->from[0]->mailbox."#".$headers->from[0]->host;
$cc=$headers->cc;
$subject=$headers->subject;
//Now get the message body
$message=$this->getBody($uid, $imap);
$email=new email();
$email->uid=$uid;
$email->datereceived=$datereceived;
$email->sender=$sender;
$email->cc=$cc;
$email->subject=$subject;
$email->message=$message;
return $email;
}
private function getHeaders($uid, $imap){
//Return an array of headers for the referenced message
//$overview = imap_fetch_overview($imap, $uid, FT_UID); //As we used the SE_UID flag when searching, we have to use it when fetching.
//We use this, rather than fetch_overview, because the overview doesn't have the cc information.
$hText = imap_fetchbody($imap, $uid, '0', FT_UID|FT_PEEK);
$headers = imap_rfc822_parse_headers($hText);
return $headers;
}
private function getBody($uid, $imap){
$body = $this->get_part($imap, $uid, "TEXT/HTML");
// if HTML body is empty, try getting text body
if ($body == "") {
$body = $this->get_part($imap, $uid, "TEXT/PLAIN");
}
return $body;
}
private function get_part($imap, $uid, $mimetype, $structure = false, $partNumber = false){
if (!$structure) {
$structure = imap_fetchstructure($imap, $uid, FT_UID);
}
if ($structure) {
if ($mimetype == $this->get_mime_type($structure)) {
if (!$partNumber) {
$partNumber = 1;
}
$text = imap_fetchbody($imap, $uid, $partNumber, FT_UID|FT_PEEK);
switch ($structure->encoding) {
case 3:
return imap_base64($text);
case 4:
return imap_qprint($text);
default:
return $text;
}
}
// multipart
if ($structure->type == 1) {
foreach ($structure->parts as $index => $subStruct) {
$prefix = "";
if ($partNumber) {
$prefix = $partNumber . ".";
}
$data = $this->get_part($imap, $uid, $mimetype, $subStruct, $prefix . ($index + 1));
if ($data) {
return $data;
}
}
}
}
return false;
}
private function get_mime_type($structure){
$primaryMimetype = ["TEXT", "MULTIPART", "MESSAGE", "APPLICATION", "AUDIO", "IMAGE", "VIDEO", "OTHER"];
if ($structure->subtype) {
return $primaryMimetype[(int)$structure->type] . "/" . $structure->subtype;
}
return "TEXT/PLAIN";
}
}
Can anyone spot something I'm missing?

You should delete OP_READONLY flag from imap_open() .
