谷歌搜索了一段時(shí)間后,我發(fā)現(xiàn)我可以使用此代碼進(jìn)行谷歌搜索：

$text=$_GET['text'];

$results=file_get_contents("http://ajax.googleapis.com/ajax/services/search/web?v=1.0&q=" . $text);

// Too lazy to use cURL

$results=json_decode($results);

問題是$results實(shí)際上是一個(gè)對(duì)象(stdClass),并且像處理數(shù)組一樣處理它不起作用(即$results [“responseData”]).這是完整的var_dump：

那么,關(guān)于如何讀取結(jié)果數(shù)組的任何線索？ (除了$results [“responseData”]之外沒有嘗試過,因?yàn)槲抑皬奈词褂眠^JSON.)
