Twitter中的PHP解析JSON流

Question

我正在玩Twitter API，但我無法解析給出的結果。

這是我的PHP代碼：

$tweets = $connection->get("https://api.twitter.com/1.1/search/tweets.json?q=%40". $hashtag .    "&count=" . $notweets); 


$new = json_encode($tweets); 
echo $new; 


foreach($new['statuses'] as $item) { 
    echo $item['text']; 
} 

答案是：

{ 
statuses: [ 
{ 
metadata: { 
iso_language_code: "ar", 
result_type: "recent" 
}, 
created_at: "Fri Dec 12 17:34:40 +0000 2014",

in_reply_to_user_id_str: null, 
in_reply_to_screen_name: null, 
} 

它要求包括hashtag #raspberrypi，我得到這個答案，我json_encode();

編碼我如何正確解析這個？我只想得到它的文本。

我不確定你的$connection->get()方法返回什麼，但是如果它的JSON字符串應該使用json_decode而不是json_encode。

$tweets = $connection->get("https://api.twitter.com/1.1/search/tweets.json?q=%40". $hashtag .    "&count=" . $notweets); 

$tweetsArray = json_decode($tweets, true); 
foreach($tweetsArray['statuses'] as $item) { 
    echo $item['text']; 
}
