     * 
     * 
     * === 第一步 ===
     * 获取你的所有域名的zone_identifier, 保存为./result_zone_id_and_domain.json
     * 可以参考：
     * 获取CloudFlare上的所有域名的ID (zone_identifier) - by PHP 
     * https://blog.csdn.net/qq285744011/article/details/88345077
     * 
     * === 第二步 ===
     * 遍历json文件里的域名，
     * 根据官方手册，先查询这个zone（和域名一对一）的现存DNS纪录
     * 再根据自己的需要，增删改查。
     * 增 https://api.cloudflare.com/#dns-records-for-a-zone-create-dns-record
     * 删 https://api.cloudflare.com/#dns-records-for-a-zone-delete-dns-record
     * 改 https://api.cloudflare.com/#dns-records-for-a-zone-update-dns-record
     * 查 https://api.cloudflare.com/#dns-records-for-a-zone-list-dns-records
     * 
     * <本文的目标>
     * 每个域名，只允许存在一条A纪录（where type = 'A' and name = 'yourdomain.com' and content = '6.6.6.6'）
     * 多了就删除，
     * 不存在就创建
     * content不是6.6.6.6的就更新为6.6.6.6 (或者先全部删除，再新建)
