PHP 利用SmartKeyQuery 抓取网页数据

//$formvars["transferCharset"] = "gb2312"; //编码
//$formvars["transferMethod"] = "GET";//请求方式
//$formvars["transferAction"] = "";//请求参数
//$action = C("JAVA_HOST") . "servlet/TransferServlet"; 访问java 控制器
$action = "http://cpc.people.com.cn/";
import("SmartKeyPost");
$smartKeyPost = new \SmartKeyPost();
$smartKeyPost->submit($action);//$formvars为提交的数组
//$smartKeyPost->submit($action, $formvars);//$formvars为提交的数组
\SmartKeyQuery::newDocumentHTML($smartKeyPost->results, 'utf-8');

$count=0;
foreach (pq(".p1_3 li")  as $li){
$po[$count]['text'] = pq($li)->find('a')->text();
$po[$count]['href'] = pq($li)->find('a')->attr('href');
$count++;
}
return $po;
}
