php高并发之php+go实现actor模型(一)
传统的php代码,调用memcache api,mysql api都会被阻塞住,这是影响并发的一个瓶颈
?
而php本身不带线程,协程,这点不好优化,so,我想到用go语言,来做后端异步处理
?
为什么要用go?编译型,有动态语言特性,内置GC,简洁,高效,内置协程,提倡share by communicating
?
系统大致流程是这样
?
php需要异步的请求缓存,db时,均将请求的信息,发送消息,给后端的go.(可以采用消息队列,也可以用socket)
?
然后php干其他事情
?
后端go接受到请求,做相应处理,查询缓存啊,db啊之类
?
待php需要使用之前异步请求的缓存,db数据时,接收从后端go发回的结果消息...
?
系统的大致流程就是这样

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
