  }]

但我想删除状态为Archived的那个人的全部数据。所以任何人都可以告诉我我该怎么做。

Answer 1

一种简单的方法是使用array_filter。

您需要先将json转换为数组：

$users = json_decode($json, true);

现在使用过滤用户数组，删除状态为Archived：

的用户

$active = array_filter($users, function($user) {
   return $user['status'] != 'Archived';
});

现在$active将是一组没有存档状态的用户。

如果你需要在json中找到结果：

$json = json_encode($active);

以下是一个工作示例：https://3v4l.org/5KMaC

Answer 2

你可以使用给定的代码，它正常工作： -

$users = json_decode($json, true);
  $count=count($users);
  for($i=0; $i<$count; $i++)
  {
      if($users->status=="Archived")
      {
         print_r($users); 
      }
  }
