You need to write the file on local disk first. Then upload it to ftp.
I have modified your code. See in line bellow.

        $ch = curl_init();
        $fp = fopen($expire, 'r');
         curl_setopt($ch, CURLOPT_URL,
'ftp://ftp_login:password@ftp.domain.com/'.$expire);
         curl_setopt($ch, CURLOPT_UPLOAD, 1);
         curl_setopt($ch, CURLOPT_INFILE, $fp);
         curl_setopt($ch, CURLOPT_INFILESIZE, filesize($expire));
        fclose($fp);
