PHP解码json并显示它

Question

我需要解码一个json文件并在页面中显示它。 我的代码不起作用，我不知道什么是错的。 输出只是一个空白页。

这是json文件。。

{
   "data": [
      {
         "name": "Jhaimee",
         "uid": 10000
      },
      {
         "name": "Ally",
         "uid": 10000133
      },
      {
         "name": "Macers",
         "uid": 1000056
      },
      {
         "name": "Diego",
         "uid": 100004
      },
      {
         "name": "Killersmile",
         "uid": 1000050
      },
      {
         "name": "Joel",
         "uid": 1000011
      }
   ]
}

我希望输出为..

Jhaimee
Ally
Macers
Diego
Killersmile
Joel

这是我的php。

$data = file_get_contents("https://graph.facebook.com/fql?q=SELECT name,uid FROM user WHERE uid IN  (SELECT  recipients FROM thread WHERE folder_id = 0 ORDER BY message_count DESC) AND uid != me() LIMIT 10&access_token=xxxx");
$data = json_decode($data, true);
echo $data[0]["name"];

Answer 1

最外面的数组键应该是数据 echo $data['data'][0]['name'] foreach($data['data'] as $person){ echo $person['name'] . "<br />\n"; }
