如何将多级值放入数据库？

如何将所有电话号码放入

使用PHP表单在MySQL数据库的Contact表中的电话字段？

将插入数据发布到数据库的插入查询是什么？

因此，如果我从该数据库生成JSON文件，它将看起来像遵循JSON格式。

{
    "contacts": [
        {
                "id": "c200",
                "name": "Ravi Tamada",
                "email": "ravi@gmail.com",
                "address": "xx-xx-xxxx,x - street, x - country",
                "gender" : "male",
                "phone": {
                    "mobile": "+91 0000000000",
                    "home": "00 000000",
                    "office": "00 000000"
                }
        },
        {
                "id": "c201",
