You can directly set a process to run continuously to poll and capture data or call API. Of course, this is more troublesome.

The simple method is that when each user visits you make a judgment whether it is time to generate new data. If there is no data when the time is up, run the relevant function once to save the data into the database. Then there will be data in the database. After that, you don’t have to catch the users who come to visit. Of course, you also need to have a simple mechanism to remove duplicates.

As for whether to crawl or directly API, it doesn’t seem to be troublesome. You can check whether websites such as aggregated data have similar interfaces.

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

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.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

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.
