// 初始化一个 cURL 对象 $curl = curl_init(); // 设置你需要抓取的URL curl_setopt($curl, CURLOPT_URL, 'http://www.cmx8.cn'); // 设置header curl_setopt($curl, CURLOPT_HEADER, 1); // 设置cURL 参数，要求结果保存到字符串中还是输出到屏幕上。 curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); // 运行cURL，请求网页 $data = curl_exec($curl); // 关闭URL请求 curl_close($curl);

//$data是curl_exec返回的的值，即采集的目标内容 preg_match_all("/
(.*?)<\/li>/",$data, $out, PREG_SET_ORDER); foreach($out as $key => $value){ //此处$value是数组，同时记录找到带匹配字符的整句和单独匹配的字符 echo '匹配到的整句：'.$value[0].' '; echo '单独匹配到的：'.$value[1].' '; }

curl_setopt($ch, CURLOPT_TIMEOUT, 60); //只需要设置一个秒的数量就可以 curl_setopt($ch, CURLOPT_NOSIGNAL, 1); //注意，毫秒超时一定要设置这个 curl_setopt($ch, CURLOPT_TIMEOUT_MS, 200); //超时毫秒，cURL 7.16.2中被加入。从PHP 5.2.3起可使用
