What code in php to organize active ftp mode?

Question

PHP

Unfortunately, the passive mode is not suitable, you must configure the active transfer mode. Now it's set up like this:

$this->ftp = ftp_connect($this->host, $this->port, self::FTP_TIMEOUT);
        if (false === $this->ftp) {
            throw new Exception('connect fail');
        }
        if (false === ftp_login($this->ftp, $this->login, $this->pass)) {
            throw new Exception('auth fail');
        }
 if ($this->activeString) {
            preg_match('/(\d{1,3})\.(\d{1,3})\.(\d{1,3})\.(\d{1,3}):(\d{1,5})/', $this->activeString, $match);
            if (count($match) == 6) {
                $hex1 = intval($match[5] / 256);
                $hex2 = $match[5] - $hex1 * 256;
                $activeString = implode(',', [
                    $match[1],
                    $match[2],
                    $match[3],
                    $match[4],
                    $hex1,
                    $hex2
                ]);
                ftp_pasv($this->ftp, false);
                $try = ftp_raw($this->ftp, 'PORT ' . $activeString);
                return $this->ftp;
            }

Something doesn't fly.
