获取百度搜索结果内容的函数方法

    public function getData($name, $page = 1)
    {
        $name = urlencode($name);//需要对关键词进行url解析,否者部分带字符的标题会返回空
        //$name = urlencode($name);
        $url = 'https://m.baidu.com/s?ie=UTF-8&wd=' . $name;
        $res = $this->curl_request($url);

        // 一，获取正文
        $reach_word = substr($res, strpos($res, '<div id="results" class="results">'), strpos($res, '<div id="page-relative" class="se-page-relative">') - strpos($res, '<div id="results" class="results">'));//截取需要的内容

        // 获取标题
        $regex1 = "/<span.*?class=".*?c-title-text.*?".*?>(.*?)</span>/is";
        preg_match_all($regex1, $reach_word, $title_matches, PREG_PATTERN_ORDER);
        $title = @$title_matches[1];
        // 获取描述
        $regex2 = "/<span data-a-46b6314e><span data-a-46b6314e>(.*?)</span></span>/is";
        preg_match_all($regex2, $reach_word, $des_matches, PREG_PATTERN_ORDER);
        $des = @$des_matches[1];

        $output['title'] = $title;
        $output['des'] = $des;

        return $output;
    }
