Question

有人可以帮助我从json获取特定项目吗？

这是我的代码

<?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

我想要什么

事实上，我只想获得

"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]"

如何只显示文字内容？

Answer 1

使用

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

Answer 2

// 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;

昨天这对我有用

Answer 3

$ tweets =   $连接 - ＆GT;获得（ “https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name=” $ twitteruser “＆安培;计数=”。$ notweets）;

返回一个对象数组，因此您可以先获取它   json_encode，如

echo $ tweets [0] - ＆gt; text;

如果您想在json_encode之后使用相同的内容，则可以执行以下操作

你的代码

echo $ json = json_encode（$ tweets）; //将你的输出放到变量

$ ARR = json_decode（$ JSON）;

echo $ arr [0] - ＆gt; text;
