5. Web crawler - PHP delayed execution problem?
Introduction: I checked online. The first is the function of the sleep series (sleep/usleep/nanosleep/time_sleep_until). First of all, there is a problem with these functions. Sleep is the hang of the current process. Starting, for example: {code...} In fact, after [waiting for 10 seconds], [then displaying two timestamps at the same time], the timestamps...

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.
