用PHP获取Google AJAX Search API 数据的代码

　　// This example request includes an optional API key which you will need to

　　// remove or replace with your own key.

　　// Read more about why it's useful to have an API key.

　　// The request also includes the userip parameter which provides the end

　　// user's IP address. Doing so will help distinguish this legitimate

　　// server-side traffic from traffic which doesn't come from an end-user.

　　$url = "http://ajax.googleapis.com/ajax/services/search/web?v=1.0&"

　　. "q=Paris%20Hilton&key=INSERT-YOUR-KEY&userip=USERS-IP-ADDRESS";

　　// sendRequest

　　// note how referer is set manually

　　$ch = curl_init();

　　curl_setopt($ch, CURLOPT_URL, $url);

　　curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

　　curl_setopt($ch, CURLOPT_REFERER, /* Enter the URL of your site here */);

　　$body = curl_exec($ch);

　　curl_close($ch);

　　// now, process the JSON string

　　$json = json_decode($body);

　　// now have some fun with the results...

　　function google_search_api($args, $referer = 'http://www.glzy8.com/', $endpoint = 'web'){

　　$url = "http://ajax.googleapis.com/ajax/services/search/".$endpoint;

　　if ( !array_key_exists('v', $args) )

　　$args['v'] = '1.0';

　　$url .= '?'.http_build_query($args, '', '&');

　　$ch = curl_init();

　　curl_setopt($ch, CURLOPT_URL, $url);

　　curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

　　curl_setopt($ch, CURLOPT_REFERER, $referer);

　　$body = curl_exec($ch);

　　curl_close($ch);

　　return json_decode($body);

　　}

　　// 使用示例

　　$rez = google_search_api(array(

　　'q' => '21andy.com', // 查询内容

　　'key' => '你申请到的API KEY',

　　'userip' => '你的IP地址',

　　));

　　header('Content-type: text/html; charset=utf-8;');

　　echo '<xmp>';

　　print_r($rez);

　　echo '</xmp>';
