原理

根据现在的标题，去请求百度下拉词显示的接口，选择下拉词的第一个词替换现在的标题

这样采集站的标题就不再和原来的千篇一律了，有助于提高SEO！

代码

$NewTitle = Get_Title($Title);
if ($NewTitle) {
    $NewTitle = Title;//如果下拉词没获取到就使用原来的标题
}
function Get_Title($Title) {
	$url = 'https://www.baidu.com/sugrec?pre=1&p=3&ie=utf-8&json=1&prod=pc&from=pc_web&wd=';
	$i = 0;
	$ArtJson = json_decode(Get_baidu($url.$Title),true);
	while(empty($ArtJson['g'][0]['q']) && $i < 50) {
		$i++;
		$ArtJson = json_decode(Get_baidu($url.$Title),true);
	}
	if($ArtJson['g'][0]['q']) {
		$newTitle = $ArtJson['g'][0]['q'];
	} else {
		$newTitle = $Title;
	}
	return($newTitle);
}
function Get_baidu($url) {
	$header = [
	        'User-Agent:'Mozilla/5.0 (iPad; CPU OS 11_0 like Mac OS X) AppleWebKit/604.1.34 (KHTML, like Gecko) Version/70.0 Mobile/15A5341f Safari/604.1',

	        'Connection: keep-alive',
	        'Host: www.baidu.com',
	    ];
	$curl = curl_init();
	curl_setopt($curl, CURLOPT_URL,$url);
	curl_setopt($curl, CURLOPT_HTTPHEADER,$header);
	curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
	curl_setopt($curl, CURLOPT_REFERER,'https://www.baidu.com/');
	curl_setopt($curl, CURLOPT_USERAGENT, $UA);
	$data = curl_exec($curl);
	curl_close($curl);
	return($data);
}
