<?php
$query = 'Nikita%20Platonenko';
$url = "http://ajax.googleapis.com/ajax/services/search/web?v=1.0&q=".$query;
$body = file_get_contents($url);
$json = json_decode($body);
for($x=0;$x<count($json->responseData->results);$x++){
echo "<b>Result ".($x+1)."</b>";
echo "<br>URL: ";
echo $json->responseData->results[$x]->url;
echo "<br>VisibleURL: ";
echo $json->responseData->results[$x]->visibleUrl;
echo "<br>Title: ";
echo $json->responseData->results[$x]->title;
echo "<br>Content: ";
echo $json->responseData->results[$x]->content;
echo "<br><br>";
}
?>
As the AJAX Api is now depreciated, you can use a third party service like SerpApito get Google results. They have a GitHubrepository, and it should be easy to integrate:
由于 AJAX Api 现在已贬值，您可以使用SerpApi等第三方服务来获取 Google 搜索结果。他们有一个GitHub存储库，应该很容易集成：
$query = [
"q" => "Coffee",
"google_domain" => "google.com",
];
$serp = new GoogleSearchResults();
$json_results = $serp.json($query);

The answer:
答案：
Here is what I use successfully:
这是我成功使用的内容：
http://ajax.googleapis.com/ajax/services/search/web?v=1.0&q=[q]&key=[key]&cx=[account]&rsz=large&userip=[userip]&start=[start]
I don't think you have full control over how many results that can be obtained in the query. But you can control the results size (rsz=large), and where it starts.
我认为您无法完全控制在查询中可以获得多少结果。但是您可以控制结果大小 ( rsz=large) 及其开始位置。
Other notes:
其他注意事项：
In addition, it is always good to include the user's ip address there. Because, Google limits the number of queries based unique ip addresses (meaning, how many from an ip address). So if they are all coming from your server, you will be limited in how many queries you can send, but the limits go way down if you send the user's ip address. In addition, caching the results for a couple of days is an added bonus.
此外，在那里包含用户的 IP 地址总是好的。因为，谷歌限制了基于唯一 ip 地址的查询数量（意思是来自一个 ip 地址的数量）。因此，如果它们都来自您的服务器，那么您可以发送的查询数量将受到限制，但是如果您发送用户的 IP 地址，则限制会降低。此外，将结果缓存几天是一个额外的好处。
