我如何遍歷並顯示FROM_USER文本特性從這個頁面:使用此代碼?:遍歷和顯示JSON性能

$json = json_decode(file_get_contents('http://search.twitter.com/search.json?q=stackexchange'));   

     foreach($json as $obj){ 
      var_dump($obj); 
     } 

http://search.twitter.com/search.json?q=stackexchange

這是本頁的var_dump():

有對象的集合存儲在數組中各含有from_usertext性質稱爲results。您可以循環這個數組,並得到屬性,像這樣:

$json = json_decode(file_get_contents('http://search.twitter.com/search.json?q=stackexchange'));   
    foreach($json->results as $result){ 
     $from_user = $result->from_user; 
     $text = $result->text; 
     echo $from_user . ' ' .$text; 
    }

+1謝謝dnapierata。您的回答對幫助我瞭解JSON非常有幫助。 – Anthony 2013-04-30 08:50:11

我真的很難看到「結果」數組。我安裝了名爲JSONview的Chrome插件來幫助我。顯然,JSONview隱藏了結果數組(見上) – Anthony 2013-04-30 09:01:12

爲了得到一個關聯數組確保您通過第二個參數的json_decode()爲「真」。 – antony 2013-04-30 03:19:04

僅供參考 - 安東尼的評論雖然正確,但不再適用於此答案,因爲我改變了它。這假定你沒有使用關聯數組,但stdObjects(這是json_decode的默認行爲) – 2013-04-30 03:21:51
