在 PHP 7.2 中，将一个树形结构的多维数组转换为二维数组的实现
1、HTTP 请求，获取租户列表(基于当前租户 ID，自根租户自上而下)，获取到一个树形结构的多维数组，无限级循环
/**
* HTTP 请求，获取租户列表(基于当前租户 ID，自根租户自上而下)
*
* @param string $groupId 租户ID
*
* @return array
* 格式如下：

* 'group_pid' => '', // 租户父级 ID
* 'group_code' => '1800000001', // 租户标识
* 'group_name' => '广东省', // 租户名称
* 'is_open' => 1, // 租户状态，0：关闭；1：开启

* [

2、获取租户列表(二维数组)，将一个树形结构的多维数组转换为二维数组
