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

What is the difference between a service container and a dependency injection container in PHP frameworks?
Article Introduction：Service containers and dependency injection containers are often mentioned in the PHP framework. Although they are related, they are different. Dependency injection containers (DICs) focus on automatically parsing class dependencies, such as injecting objects through constructors without manual instantiation. The service container extends its functions on this basis, including binding interfaces to specific implementations, registering singletons, managing shared instances, etc. When using it, if the class dependency resolution or cross-frame scenarios are discussed, it should be called DIC; if it involves service management within the framework, it is called a service container. The two are often integrated in modern frameworks, but understanding their differences can help to gain a deep understanding of the framework mechanism.

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.

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

What is a Dependency Injection Container (DIC) and why use one in PHP?
Article Introduction：Dependency Injection Container (DIC) is a tool that manages and provides object dependencies for use in PHP projects. The main benefits of DIC include: 1. Decoupling, making components independent, and the code is easy to maintain and test; 2. Flexibility, easy to replace or modify dependencies; 3. Testability, convenient for injecting mock objects for unit testing.

Deep dive into the Laravel Service Container and Dependency Injection
Article Introduction：Laravel's service container is a core tool for managing class dependencies and executing dependency injection. It simplifies code development and maintenance by automatically instantiating objects and their recursive dependencies. 1. The service container is like a "factory" that can automatically create and pass the required objects; 2. Support constructor injection (most commonly used), method injection (used in the controller type prompt), and setter injection (suitable for optional dependencies); 3. The binding methods include simple binding, singleton binding, and interface binding implementation classes to achieve decoupling; 4. In most cases, the container automatically resolves dependencies, and can also manually obtain instances through app() or make(); 5. Alias ??can be set for the binding and the binding is registered by the service provider to improve the application organizational structure and maintainability.

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.
