operator_id=86&operator_password=951自己的做法：
$cookie_jar = dirname(__FILE__)."/pic.cookie";
$post = "operator_id=86&operator_password=951";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://10.30.68.11/login_check.php");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
