从百度百科抓取内容

<?php//echo getbaike('马化腾'); //输出 http://baike.baidu.com/view/1466380.htmfunction getEncyclopediaInfo($name){    $name_gbk = iconv('utf-8', 'gbk', $name); //将字符转换成GBK编码，若文件为GBK编码可去掉本行    $encode = urlencode($name_gbk); //对字符进行URL编码    $url = 'http://baike.baidu.com/list-php/dispose/searchword.php?word=' .$encode. '&pic=1';    $get_contents = httpGetRequest_baike($url); //获取跳转页内容    $get_contents_gbk = iconv('gbk', 'utf-8', $get_contents); //将获取的网页转换成UTF-8编码，若文件为GBK编码可去掉本行    preg_match("/URL=(\S+)'>/s", $get_contents_gbk, $out); //获取跳转后URL    $real_link = 'http://baike.baidu.com' .$out[1];    $get_contents2 = httpGetRequest_baike($real_link); //获取跳转页内容    preg_match('#"Description"\scontent="(.+?)"\s\/\>#is', $get_contents2, $matchresult);    if (isset($matchresult[1]) && $matchresult[1] != ""){        return $matchresult[1];    }else{        return "抱歉，没有找到与“".$name."”相关的百科结果。";    }}function httpGetRequest_baike($url){    $headers = array(        "User-Agent: Mozilla/5.0 (Windows NT 5.1; rv:14.0) Gecko/20100101 Firefox/14.0.1",        "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",        "Accept-Language: en-us,en;q=0.5",        "Referer: http://www.baidu.com/"    );    $ch = curl_init();    curl_setopt($ch, CURLOPT_URL, $url);    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);    $output = curl_exec($ch);    curl_close($ch);    if ($output === FALSE){        return "cURL Error: ". curl_error($ch);    }    return $output;}?>

微信中调用
