如何从JSON获取特定值？

任何人都可以帮助我从json获取特定项目吗？如何从JSON获取特定值？

这里是我的代码

<?php 
    require_once("../twitter/twitteroauth.php"); //Path to twitteroauth library 
    $twitteruser = "SokSovat"; 
    $notweets = 1; 
    $consumerkey = "XXXXX"; 
    $consumersecret = "XXXXXX"; 
    $accesstoken = "XXXXXXX"; 
    $accesstokensecret = "XXXXXXX"; 

    function getConnectionWithAccessToken($cons_key, $cons_secret, $oauth_token, $oauth_token_secret) { 
     $connection = new TwitterOAuth($cons_key, $cons_secret, $oauth_token, $oauth_token_secret); 
     return $connection; 
    } 

    $connection = getConnectionWithAccessToken($consumerkey, $consumersecret, $accesstoken, $accesstokensecret); 

    $tweets = $connection->get("https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name=".$twitteruser."&count=".$notweets); 

    echo json_encode($tweets); 

?>

输出

我想

事实上，我想只有

什么

"text":"\u3050\u308b\u306a\u3073\u98df\u5e02\u5834\u3067\u7523\u5730\u76f4\u9001\u30fb\u7279\u7523\u54c1\u3001\u53b3\u9078\u30bb\u30ec\u30af\u30c8\u3057\u305f\u30b0\u30eb\u30e1\u3092\u304a\u53d6\u308a\u5bc4\u305b\uff01 http:\/\/t.co\/IQRCSt2sFC\n[PR]"

如何只显示文本内的内容？

如果'$ twitteruser'来自请求，在' - > get（）'中使用'urlencode（）'之前是明智的。 –

使用

echo json_encode($tweets[0]['text']);

OP想要从'JSON'获取特定项目，而不是将特定项目编码为'JSON'。 –

@YogeshSuthar再次读取OP代码:) api返回数组 – DevZer0

@ DevZer0这有问题'任何人都可以帮我从json获取特定项目吗？'。 –

// decode json result to access each key in the array 
$la_data = json_decode($tweets); 

$lo_tweet = reset($la_data); 

if (!is_object($lo_tweet)) 
    exit; 

echo $lo_tweet->text;

这为我工作就在昨天

$鸣叫= $连接 - > GET（ “https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name=”。$ twitteruser。 “&计数=”。 $ notweets）;

返回对象的数组，所以你可以简单地前 json_encode得到它，就像

回声$鸣叫[0] - >文本;

如果你希望你的json_encode后一样，你可以做以下

代码

回声$ JSON = json_encode（$鸣叫）; //将你的输出放到变量中

$ arr = json_decode（$ json）;

echo $ arr [0] - > text;
