复制代码 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：

由此，我们可以写个函数像这样

复制代码 代码如下:

function google_search_api($args, $referer = 'http://www.jb51.net/', $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>';
