鉴于大家对PHP十分关注，我们编辑小组在此为大家搜集整理了“用PHP获取Google AJAX Search API 数据的代码”一文，供大家参考学习
http://code.google.com/apis/ajaxsearch/documentation/#fonje
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：
http://code.google.com/apis/ajaxsearch/signup.html
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>'';
