javascript - Unable to catch exception after php throws it
It cannot be caught after php throws an exception. This is an error of WeChat. The third-party class I called, the third-party class throws an exception, but I cannot catch it here.
Call other class methods, this class throws an exception, which cannot be caught in the calling class.
Methods that throw exceptions
Catch exceptions
I feel like I can’t catch it
No matter what is output in my catch, this error always occurs, and my code cannot be executed. I want to throw an exception and then handle my code and then execute it.
Because this is a foreach. When one of them has an error, the following loop will not work. It will be executed

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.
