來獲取值：

$code = json_decode($json,true); 
foreach($code as $arr) { 
    foreach($arr as $k=>$v) { 
     $rt_count = $arr[$k]['rt_count']; 
    } 
}

現在拿到實體 - > URL

$img_url = $arr[$k]['entity']['url'];

是這個正確的方式？

JSON字符串是無效的首先。在這種情況下，json_decode（）將返回NULL。 –

你可以只是這樣做：

$code = json_decode($json); 
$img_url = $code->results[0]->entity[0]->url;

有通過無需循環，除非你是拉幾個實體和你的JSON就是不完整的。

我得到了幾個結果，並希望爲它做所有 –

試試這個。這會工作。

foreach($code['results'] as $result){ 
    foreach($result['entity'] as $entity){ 
    $img_url = $entity['url']; 
    echo $img_url . ' '; 
    } 
}

@Jinging：你能看到我更新的闕。我需要爲每個結果分別獲取每個img –

是的，這會爲每個結果獲取img。它們被一個空格分隔（'echo $ img_url。'';'）。 –

首先你的json字符串不正確。錯誤結束括號。我糾正了這一點。檢查下面： -

$json = '{"status":"ok", 
"message":"Success v1.", 
"remainingquota":"200", 
"results":[ 

    { 
     "timestamp":"2014-01-24 23:26:55",

     "tweet_text":"#Respect. 5 year old Hari Charan Rao participated in Mumbai marathon, on a prosthetic leg -> http://t.co/8YknB78WOU", 
     "title":"#Respect. 5 year old Hari Charan Rao participated in Mumbai marathon, on a prosthetic leg -> http://t.co/8YknB78WOU", 
     "city":"mumbai", 
     "rt_count":"43", 
     "sentiment":"0", 
     "powertweet":"0", 
     "entity":[ 
      { 
       "url":"http://pbs.twimg.com/media/Bev6USHCAAAH5a8.png", 
       "type":"img", 
       "info":{ 
        "type":"img", 
        "h":260, 
        "w":339 
         } 
      } 
       ] 
     } 
     ] 
}'; 


$code = json_decode($json,true); 
echo "<pre>";print_r($code);echo "<pre>";

如果你只想得到這個「http://pbs.twimg.com/media/Bev6USHCAAAH5a8.png」，那麼下面這一行會給你完美的結果： -

echo $code["results"][0]["entity"][0]["url"];

謝謝，但在這種情況下，它始終打印相同的圖像網址。我把'我= 0'和增量獲得每個網址，但不工作 –

每個網址意味着什麼？ – ripa

請參閱我的更新。我有一套結果。對於每個結果，我想要推文，標題，情緒，實體 - >網址。 –
