ignore_user_abort();

set_time_limit(0);

$interval = 60*5;

do{

$url = "http://www.sina.com.cn/";

$ch = curl_init();//创建一个新的curl会话

curl_setopt($ch,CURLOPT,$url);//设置需要抓取的cURL

curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);

//设置cURL参数,要求结果保存到字符串还是页面(1或真表示保存而不输出)

curl_setopt($ch,CURLOPT_TIMEOUT,2);//最大延续2秒

$result = curl_exec($ch);//执行

curl_close($ch);//关闭

sleep($interval);//休息5分钟

}while(true);

?>
