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);
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_jar);
$result=curl_exec($ch);
var_dump($result);
curl_close($ch);

可以将你的curl的代码进行封装，将url和param作为两个参数，调用的时候直接传入你需要模拟登陆的url和需要传递的参数就可以了
