本文实例讲述了PHP访问Google Search API的方法。分享给大家供大家参考。具体如下：
这段代码段演示了如何从php向AJAX搜索API发送请求。请注意，此示例假定使用 PHP 5.2。对于较早安装的 PHP，请参考对应的官方注释。
具体代码如下：
代码如下:
$url = "http://ajax.googleapis.com/ajax/services/search/web?v=1.0&q=Paris%20Hilton";
// 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, "http://www.mysite.com/index.html");
$body = curl_exec($ch);
curl_close($ch);
// now, process the JSON string
$json = json_decode($body);
// now have some fun with the results...
// 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, "http://www.mysite.com/index.html");
$body = curl_exec($ch);
curl_close($ch);
// now, process the JSON string
$json = json_decode($body);
// now have some fun with the results...
希望本文所述对大家的php程序设计有所帮助。
