How to Implement Dependency Injection in PHP
Article Introduction：Implementing dependency injection (DI) in PHP can be done by manual injection or using DI containers. 1) Manual injection passes dependencies through constructors, such as the UserService class injecting Logger. 2) Use DI containers to automatically manage dependencies, such as the Container class to manage Logger and UserService. Implementing DI can improve code flexibility and testability, but you need to pay attention to traps such as overinjection and service locator anti-mode.

Is Your PHP Switch a Code Smell? Identifying and Refactoring Anti-Patterns
Article Introduction：Yes, the switch statement in PHP itself is not a code smell, but when it is repeated in multiple files, contains too many branches, is tightly coupled with business logic, violates the principle of single responsibility, or makes judgments based on object types, it becomes an anti-pattern; 1. Use policy mode processing factory: define processing interfaces and concrete classes, map types to processors through factory mapping, add new types only requires registration and no modification of existing code; 2. Use class-based distribution (polymorphism): let the object itself determine behavior, implement concrete logic by inheriting abstract classes, and directly execute methods when calling without switching; 3. Use closure mapping (suitable for simple scenarios): Use associative arrays to store the mapping of type to closures, avoid branch structure but are less testable; 4. PHP8 can be used
