Getting Gmail emails in read status with Imap PHP - php

Question

I take data from Gmail with this code
<?php $data = array(
// email account
'email' => array(
'hostname' => '{imap.gmail.com:993/imap/ssl}INBOX',
'username' => $emailAddress,
'password' => $emailPassword
),
// inbox pagination
'pagination' => array(
'sort' => $sortBy,
'limit' => 10,
'offset' => $offset
)
);
$result = array();
$imap = imap_open($data['email']['hostname'], $data['email']['username'], $data['email']['password']) or die ('Cannot connect to yourdomain.com: ' . imap_last_error());
$read = imap_search($imap, 'ALL');
$overview = imap_fetch_overview($imap, $read[$i], 0);
$header = imap_headerinfo($imap, $read[$i], 0);
$mail = $header->from[0]->mailbox . '#' . $header->from[0]->host;
$image = '';
$structure = imap_fetchstructure($imap, $read[$i]);
if(isset($structure->parts) && is_array($structure->parts) && isset($structure->parts[1])) {
$part = $structure->parts[1];
if($part->encoding == 3) {
$message = imap_fetchbody($imap,$read[$i],1.2);
$message = imap_qprint($message);
} else if($part->encoding == 1) {
$message = imap_8bit($message);
} else {
$message = imap_fetchbody($imap,$read[$i],2);
$message = imap_qprint($message);
}
}else{
$message = imap_body($imap, $read[$i],0);
}
?>
All data I receive correctly, however when I enter Email list page, the received emails turn to read.
It worked fine before, after using for some time, this issue appeared.
Any idea what can be the reason?

In imap_fetchbody, add the FT_PEEK flag to prevent clearing the \Seen flag automatically.
imap_fetchbody($imap, $read[$i], 1.2, FT_PEEK);
See option flag documentation at the official site.
