Hi need some help i am new to cURL,i am trying to scrap data from http://www.ugbettingforum.co.uk,

$md5Pass = md5($pass);
$data = "do=login&url=%2Findex.php&vb_login_md5password=$md5Pass&vb_login_username=$user&cookieuser=1";
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, "http://www.ugbettingforum.co.uk/login.php?do=login"); // replace ** with tt
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.3; WOW64; rv:32.0) Gecko/20100101 Firefox/32.0");
curl_setopt ($ch, CURLOPT_TIMEOUT, '10');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch,CURLOPT_POSTFIELDS,$data);
curl_setopt($ch, CURLOPT_COOKIEJAR, "/cookie.txt");
curl_setopt($ch, CURLOPT_COOKIEFILE, "/cookie.txt");
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
$store = curl_exec ($ch);
