$info=file_get_contents($url);
echo $info;
?>


我想获取百度竞价排名前三的几个站,使用file_get_contents输出了百度搜索结果页的内容但是为什么竞价内容不显示啊?

原来是 这个的有竞价位的

但是我输出的 就没有了竞价内容了请问下各位高手是什么原因啊?

<?php	$url = 'http://www.baidu.com/s?rsv_bp=0&rsv_spt=3&ie=utf-8&rsv_sug3=23&rsv_sug4=267&rsv_sug1=22&rsv_sug2=0&inputT=18&wd=%E4%BF%9D%E5%81%A5%E5%93%81&tn=89040009_1_pg';    $ch = curl_init();    curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/31.0.1650.63 Safari/537.36');    curl_setopt($ch, CURLOPT_URL, $url);    curl_setopt($ch, CURLOPT_HEADER, 0);    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);    $content = curl_exec($ch);    curl_close($ch);	echo $content;

大概检查了下,百度验证了user-agent,如果为空就没有竞价那一块

需要模???器user-agent??。

header('Content-type: text/html;charset=utf-8');$url = 'http://www.baidu.com/s?wd=%E4%BF%9D%E5%81%A5%E5%93%81&rsv_spt=1&issp=1&f=8&rsv_bp=0&rsv_idx=2&ie=utf-8&tn=baiduhome_pg&rsv_enter=0&inputT=2625&rsv_pq=f8ac4a3700000dd9&rsv_t=54ffCzY5xNXYlNcEjuJTNfBzIrJob0iUn2whzhsN7JtTaA6R0Z7yxIGlNFSR5t0vyOID&rsv_sug3=5&rsv_sug1=4&rsv_sug2=0&rsv_sug4=4274';  $opts = array(   'http'=>array(     'user_agent' => $_SERVER['HTTP_USER_AGENT']  ) ); $context = stream_context_create($opts);$info=file_get_contents($url, false, $context);echo $info;
