我推荐使用4个关联表来达到最灵活有效的实现。
type 表
id, name
type_attribute 表
id, type_id(关联type表的id),name,...(可以定义一些属性，比如多选，必选之类)
type_attribute_option 表
id, attribute_id(关联type_attribute表的id),name
relation 表
id, goods_id(商品的id),attribute_id(关联type_attribute的id),attribute_option(关联type_attribute_option的id)
那么剩下的就很简单了。就按照你第二个例子里面的电影网站为例，
type 顾名思义就是种类了，电影就是一种大的种类
type_attribute 就是类型里面的一些属性，比如电影有类型，年代，地区，语言，属性什么的。
type_attribute_option 就是这些属性的一些选项，比如年代有 2015,2014
然后每个电影使用 relation 表来和 attribute 和 option 关联就可以了。

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
