Backend positioning - Should I use PHP or Java to implement the positioning and navigation function in the cloud?
The company needs to implement positioning and navigation function (indoor positioning and navigation) in the cloud. Currently, there are two backends using java and php. I used javaweb to do the positioning and navigation, but I have never done javaweb before, so I just watched it for a few days and implemented it. Simple version. Now if I want to further improve this part of the function, I will definitely have to recruit people if I continue to use java web, and the workload will not be saturated if I only do this part of the work. Is it possible to do this with php? Is there any implementation of these algorithms in PHP? Will the performance be poor? If there is no problem with PHP, he can do other business of the company in the future (developed with PGP).

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

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.
