我对网站进行了抓取登录信息，怎样才能进行实时监控？只要是登录，程序就自动抓取。
$ch = curl_init();
$time=time();
$times=time()+5;
$timeout = 10; // set to zero for no timeout
curl_setopt ($ch, CURLOPT_URL,'http://');
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.131 Safari/537.36');
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$html = curl_exec($ch);
//echo $html;
$web=json_decode($html);
$ip_m=M('wzip');
$arr=array();
foreach($web as $k=>$v){
$arr[$k]=$v;
}
$user = json_decode(json_encode($arr[$k]),true);
$ip_m->addAll($user);
