memcached,该怎么处理
memcached
在网上看到memcached架构设计方案
缓存分为两级，第一级只是一个PHP数组，有效范围是Request。而第二级是memcached。这么做的原因是，很多数据在一个Request周期内需要加载多次，这样可以减少memcached的网络请求。另外我们的框架也会尽可能的发送memcached的gets命令来获取数据， 从而减少网络请求
谁能给个例子，或者伪代码实现一下？

不知道你是从哪里看来的奇葩的方案
如果 php 的数组可以用于缓存的话，那要 memcached 做什么？

跑偏了。。

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,
