代码如下:

// 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... 
 
API KEY 申请地址： 
http://code.google.com/apis/ajaxsearch/signup.html 

由此，我们可以写个函数像这样 
 代码如下:

function google_search_api($args, $referer = 'http://www.gxlcms.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 
$rez = google_search_api(array( 
'q' => '21andy.com', // 查询内容 
'key' => '你申请到的API KEY', 
'userip' => '你的IP地址', 
)); 
header('Content-type: text/html; charset=utf-8;'); 
echo '&#39;; <BR />print_r($rez); <BR />echo &#39;';
