php中抓取网页内容的实例详解
方法一:使用file_get_contents方法实现$url = "http://news.sina.com.cn/c/nd/2016-10-23/doc-ifxwztru6951143.shtml";
$html = file_get_contents($url);
//如果出现中文乱码使用下面代码
//$getcontent = iconv("gb2312", "utf-8",$html);
echo "".$html."";
方法二:使用curl实现$url = "http://news.sina.com.cn/c/nd/2016-10-23/doc-ifxwztru6951143.shtml";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
$html = curl_exec($ch);
curl_close($ch);
echo "".$html."";
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
加上这句代码,表示如果请求被重定向时,可以访问到最终的请求页面,不然请求的结果会显示如下内容:
Object movedObject Moved
