PHP Dependency Injection: Boost Code Maintainability
Article Introduction：Dependency injection provides object dependencies through external injection in PHP, improving the maintainability and flexibility of the code. Its implementation methods include: 1. Constructor injection, 2. Set value injection, 3. Interface injection. Using dependency injection can decouple, improve testability and flexibility, but attention should be paid to the possibility of increasing complexity and performance overhead.

Best Practices for Dependency Injection in PHP
Article Introduction：The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.

PHP Master | Dependency Injection with Pimple
Article Introduction：Core points
Dependency injection is a key concept in application development, and by injecting dependencies into modules rather than hard-code them, you can write more efficient and more maintainable code.
Pimple is a simple dependency injection container that uses PHP's closure to define dependencies in a manageable way, helping to keep your code maintainable.
Two main techniques for injecting dependencies are constructor-based dependency injection and setter-based injection, each with its own advantages and disadvantages.
Pimple supports the DRY principle of software development by acting as a container that defines dependencies, avoiding duplication, making it easier to manage and centralize services in applications.
Pimple also offers advanced features such as using sharing

How to Build Your Own Dependency Injection Container
Article Introduction：This article discusses how to build a simple dependency injection container (DI container) PHP package. All code in the article, including PHPDoc annotations and unit tests (100% code coverage), has been uploaded to the GitHub repository and listed on Packagist.
Key points:
Building DI containers helps developers understand the basic principles of dependency injection and the working mechanism of containers.
DI containers have two main functions: "dependency injection" and "container". It needs to be able to instantiate and include services using constructor injection or setter injection methods.
Symfony dependency injection containers can be used as a reference for creating custom containers. It divides container configuration into parameters and services, allowing secure storage

How Does Dependency Injection Improve Testability in PHP?
Article Introduction：This article examines how Dependency Injection (DI) improves PHP testability. DI decouples classes, enabling easy mocking of dependencies for isolated unit testing. However, pitfalls like over-mocking and inconsistent DI implementation can hinder i

Explain Angular dependency injection
Article Introduction：Dependency injection (DI) is the core mechanism of the Angular framework, which reduces inter-class coupling by providing dependencies externally rather than creating them by itself. 1. DI automatically passes dependency instances through constructor parameters, such as constructor(privateservice:DataService); 2. Angular supports multi-level injectors: root injector (providedIn:'root') provides global singleton services, module/component-level injectors limit service scope; 3. Common injection methods include constructor injection (most commonly used), attribute injection and method parameter injection; 4. Notes include avoiding circular dependencies, preventing duplicate services from causing non-singleton problems, and using APP_I
