This is a missing feature, see the PHP bug #53043 : http://bugs.php.net/bug.php?id=53043
A example code using directly the IMAP protocol:
<?php
declare(strict_types=1);
class ImapSocket
{
private $socket;
public function __construct($options, $mailbox = '')
{
$this->socket = $this->connect($options['server'], $options['port'], $options['tls']);
$this->login($options['login'], $options['password']);
if ($mailbox !== null) {
$this->select_mailbox($mailbox);
}
}
private function connect(string $server, int $port, bool $tls)
{
if ($tls === true) {
$server = "tls://$server";
}
$fd = fsockopen($server, $port, $errno);
if (!$errno) {
return $fd;
}
else {
throw new \Exception('Unable to connect');
}
}
private function login(string $login, string $password): void
{
$result = $this->send("LOGIN $login $password");
$result = array_pop($result);
if (substr($result, 0, 5) !== '. OK ') {
throw new \Exception('Unable to login');
}
}
public function __destruct()
{
fclose($this->socket);
}
public function select_mailbox(string $mailbox): void
{
$result = $this->send("SELECT $mailbox");
$result = array_pop($result);
if (substr($result, 0, 5) !== '. OK ') {
throw new \Exception("Unable to select mailbox '$mailbox'");
}
}
public function get_flags(int $uid): array
{
$result = $this->send("FETCH $uid (FLAGS)");
preg_match_all("|\\* \\d+ FETCH \\(FLAGS \\((.*)\\)\\)|", $result[0], $matches);
if (isset($matches[1][0])) {
return explode(' ', $matches[1][0]);
}
else {
return [];
}
}
private function send(string $cmd, string $uid = '.')
{
$query = "$uid $cmd\r\n";
$count = fwrite($this->socket, $query);
if ($count === strlen($query)) {
return $this->gets();
}
else {
throw new \Exception("Unable to execute '$cmd' command");
}
}
private function gets()
{
$result = [];
while (substr($str = fgets($this->socket), 0, 1) == '*') {
$result[] = substr($str, 0, -2);
}
$result[] = substr($str, 0, -2);
return $result;
}
}
Usage:
<?php
$imap = new ImapSocket([
'server' => 'localhost',
'port' => 143,
'login' => 'login',
'password' => 'secret',
'tls' => false,
], 'INBOX');
var_dump($imap->get_flags(0));
