使用PHP来简单的创建一个RPC服务

壹小俊发布时间：2020-03-30 09:06:32 ，浏览量：3

RPC全称为Remote Procedure Call，翻译过来为"远程过程调用"。主要应用于不同的系统之间的远程通信和相互调用。

比如有两个系统，一个是PHP写的，一个是JAVA写的，而PHP想要调用JAVA中的某个类的某个方法，这时候就需要用到RPC了。

怎么调？直接调是不可能，只能是PHP通过某种自定义协议请求JAVA的服务，JAVA解析该协议，在本地实例化类并调用方法，然后把结果返回给PHP。

这里我们用PHP的socket扩展来创建一个服务端和客户端，演示调用过程。

RpcServer.php代码如下：
