php获取百度下拉词
Madman有些时候在做SEO的时候想要使用程序来自动修改标题，这时候可以用到百度下拉词库来自动匹配修改，以下是一段获取百度词库的PHP代码
//获取百度下拉信息
$title = urlencode($data['title']);
$api = "https://www.baidu.com/sugrec?pre=1&p=1&ie=utf-8&prod=pc&csor=2&wd=".$title."";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $api);
curl_setopt($ch, CURLOPT_TIMEOUT, 5);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$r = curl_exec($ch);
curl_close($ch);
$r = json_decode($r,true);
if(empty($r['g'])){
$new_title = $data['title'].'(图文)';
}
//数据一定存在，取出数据，然后随机获取一个
$baidu_title = $r['g'][mt_rand(0,count($r['g'])-1)]['q'];//数据的随机获取
$baidu_title2 = $r['g'][mt_rand(0,count($r['g'])-1)]['q'];//数据的随机获取
$baidu_title = $baidu_title==$data['title']?$r['g'][mt_rand(0,count($r['g'])-1)]['q']:$baidu_title;//数据随机，防止与原标题一样
$baidu_title2 = $baidu_title==$baidu_title2?$r['g'][mt_rand(0,count($r['g'])-1)]['q']:$baidu_title2;//数据随机，防止与第一个百度标题一样
