严格的讲，不是一个层次的概念。
广义的RPC与MQ并列，属于系统间交互的两大方式。可以简单认为webservice属于广义的RPC的一种，当然还有xml-rpc、json-rpc。
如果是xml-rpc可以算webservice 反过来还真不清楚
可以这么认为,我理解RPC(Remote Process Call)是远程进程调用,不管你通过HTTP协议也要，Socket协议也罢，能够调用远程规定好的接口就可称之为RPC。
很少对这类问题感兴趣，但我曾经读过这样一篇文章：
1998年，一个叫UserLand的小公司的一位牛人Dave Winer设计了XML-RPC,因为跟XML沾边，所以立刻就被微软看好了。这个XML-RPC最初其实就叫做SOAP，直到被微软看上并派人去一起合作。很快他们完成了最早的实现，并被改名为XML-RPC。
好了现在实现上没有问题了，但要推广，还是标准化一下比较好，于是微软把IBM, Oracle, Sun, Apple, Netscape等找来说我们一起把它标准化吧，这样我们大家就一起可以用它赚钱了，于是SOAP就这样形成了。
但大家知道，这些大厂商们制定标准那是各怀鬼胎啊，微软怎么可能把便宜就这么好心的让给其他人分享呢？所以SOAP标准里面除了一丁点的通用部分外，还包括允许私有扩展的内容。而且微软在这个制定过程中，已经开始做这部分内容了，所以SOAP刚刚出来，微软就抢先其他人推出了成熟的WebService产品。这就是后来大家在.NET 1.0中看到的WebService。

WebService可以理解为实现RPC的一种方式，传输数据格式为XML。

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,
