php - Json php 格式的数据

Question

我有一个像这样的 json 文件

{
  "id": "123456789012345", 
  "members": {
    "data": [
      {
        "name": "Dylan John", 
        "administrator": false, 
        "id": "12341234"
      }, 
      {
        "name": "Test user", 
        "administrator": false, 
        "id": "43214321"
      }, 
      {
        "name": "Demo user", 
        "administrator": false, 
        "id": "55445544"
      }, 
      {
        "name": "Fake user", 
        "administrator": false, 
        "id": "11991199"
      }
    ], 
    "paging": {
      "next": "www.123456demo12345.com"
    }
  }
}

我需要提取每个名称的 id。

我只是像这样启动我的 php 代码，但只显示主 ID:

<?php
$url = "http://www.1234demo1234fake.com/user.json";

$json = file_get_contents($url);
$data = json_decode($json, TRUE);

echo $data[id]; //echo master id
echo $data[members][data][id];
?>

Answer 1

您必须迭代 $data['members']['data'] 并打印 $data['members']['data'][$i][' id']。
