Question

我正在使用体育雷达API来获取NFL第1周的时间表。API以json格式（例如，我缩短了字符串）返回以下数据。

"id": "8e45fe2d-fb95-4504-845d-7c815623ccd6",

I used the following website作为有关如何仅显示我需要的数据以及如何遍历它们的教程

请注意，JSON字符串存储在变量$schedule

中

我的代码

   // JSON string
      $jsonData = $schedule; //get json string

      // Convert JSON string to Array
      $jsonArray = json_decode($jsonData, true);


      // Convert JSON string to Object
      $jsonObject = json_decode($schedule);

遍历PHP数组或对象

$someArray = $jsonArray
  foreach ($someArray as $key => $value) {
    echo $value["home"] . ", " . $value["away"] . "<br>";
  }

  // Loop through Object
  $someObject = jsonObject
  foreach($someObject as $key => $value) {
    echo $value->home . ", " . $value->away . "<br>";
  }

我的错误

当尝试将字符串转换为数组并尝试获取away团队名称时，出现错误非法字符串偏移与home相同的问题，并且所有其他数据

尝试将数据作为对象访问时，出现以下错误Trying to get property of non-object

我按照教程讲了这封信。但是我得到上面的基本错误...吗？任何帮助和解释将不胜感激。谢谢

编辑：

var_export($schedule)返回以下内容：

array ( 'id' => '8e45fe2d-fb95-4504-845d-7c815623ccd6', 'year' => 2018, 'type' => 'REG', 'name' => 'REG', 'week' => array ( 'id' => '37435167-5cf6-4cce-b405-ff0e264ced9c', 'sequence' => 1, 'title' => '1', 'games' => array ( 0 => array ( 'id' => '0822b924-eadc-4398-bfe6-83cbbf3a2912', 'status' => 'scheduled', 'reference' => '57570', 'number' => 4, 'scheduled' => '2018-09-09T17:00:00+00:00', 'entry_mode' => 'INGEST', 'venue' => array ( 'id' => '6ed18563-53e0-46c2-a91d-12d73a16456d', 'name' => 'Lucas Oil Stadium', 'city' => 'Indianapolis', 'state' => 'IN', 'country' => 'USA', 'zip' => '46225', 'address' => '500 South Capitol Avenue', 'capacity' => 67000, 'surface' => 'artificial', 'roof_type' => 'retractable_dome', ), 'home' => array ( 'id' => '82cf9565-6eb9-4f01-bdbd-5aa0d472fcd9', 'name' => 'Indianapolis Colts', 'alias' => 'IND', 'game_number' => 1, ),

您正在处理数组数组。尝试这样的事情：

  $someArray = $jsonArray
  foreach ($someArray as $key => $value) {
    echo $value["home"]["name"] . ", " . $value["away"]["name"] . "<br>";
  }

从API获取JSON数据作为数组或对象
