【问题描述】:
我正在使用sports-radar API 来获取NFL 第1 周的赛程。API 以json 格式返回以下数据(例如我缩短了字符串)。

I used the following website 作为教程,介绍如何仅显示我需要的数据以及如何遍历它
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);
循环遍历 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 . ", " . $value->away . "<br>";
}
我的错误
当尝试将字符串转换为数组并尝试获取 away 团队名称时,我收到错误 Illegal string offset 'away' 同样的问题 home 和所有其他数据
当尝试将数据作为对象访问时,出现以下错误Trying to get property of non-object
我完全按照教程进行操作。然而我得到了上面的基本错误......?任何帮助和解释将不胜感激。谢谢
编辑:
var_export($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, ),
【问题讨论】:
-
只执行此操作
$schedule = json_decode($jsonData, true);,现在检查var_export($schedule);以检查away存在于哪个索引处,然后尝试调整foreach()代码 -
好的,给我一秒钟检查一下,我会回复你的。谢谢
-
做一个
var_dump($someArray)...让我们看看你有什么。 -
您不能将 $value->home 和 $value->away 转换为字符串,因为它们都是对象。
-
您的代码已将
$someObject = jsonObject更正为$someObject = $jsonObject
