PHP搜索多維數組從JSON的特定值

我想從具有最高'字節'值的對象'名稱'值。到目前爲止我的代碼是：PHP搜索多維數組從JSON的特定值

<?php 

$str = file_get_contents('https://yivesmirror.com/api/spigot'); 

$json = json_decode($str, true); 

echo get_highest($json); 

function get_highest($json) 
{ 
    foreach($json as $key => $val) 
    { 
     if (is_array($val)) $json[$key] = get_highest($val); 
    } 
    sort($json); 

    return array_pop($json); 
} 

?>

從這個JSON文件：

{ 
    "spigot-1.12-R0.1-SNAPSHOT-b1364.jar": { 
     "name": "spigot-1.12-R0.1-SNAPSHOT-b1364.jar", 
     "size": { 
      "human": "40.52MB", 
      "bytes": 42488067 
     }, 
     "date": { 
      "human": "July 25, 2017", 
      "epoch": 1501040531 
     } 
    } 
}, 
{ 
    "spigot-api-1.12-R0.1-SNAPSHOT-shaded-b1364.jar": { 
     "name": "spigot-api-1.12-R0.1-SNAPSHOT-shaded-b1364.jar", 
     "size": { 
      "human": "4.10MB", 
      "bytes": 4297941 
     }, 
     "date": { 
      "human": "July 25, 2017", 
      "epoch": 1501040531 
     } 
    } 
}

不幸的是，這是搜索所有按鍵和給我的「時代」的值不是「字節」值。我如何能：

只能從'字節'對象找到最高值？
從它發現最大的「字節」值（如上所述）獲取'name'值？

從json_decode（）中刪除「true」，以便獲取對象。然後你可以使用OOP符號！ –

由於您的問題已被擱置，我不知道如何給您答案，但在測試中，我發現有時會出現一個名爲「spigot-latest.jar」的元素，它看起來完全包含您想要的內容。否則，這個網址會顯示我做了什麼來獲取信息。它在輸出結尾顯示源。 https://iconoun.com/demo/temp_snl.php –

謝謝雷！這正是我所追求的，並感謝您對每個功能的評論！ – SuperNovaLite

當我運行你的PHP它給了我：
Notice: Undefined index: urls in C:\xampp\htdocs\FOLDER\FILE

但是，當我改變了

$json = json_decode($str, true);

到

$json = var_dump(json_decode($str, true));

重拍的$version VAR使用$version = $json['urls']['free']

然後我寫道：echo $version ，它給了我：

UPDATE：
如果從$json = json_decode($str, true);

然後你刪除true參數代碼應該工作
