Course 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.

Course Introduction：Dependency injection (DI) makes PHP code easier to test and maintain by reducing tight coupling between components. Its core advantages include: 1. Simplify unit testing, allowing injection of simulated objects to replace real services, avoid side effects, and improve testing speed and reliability; 2. Promote loose coupling, making the class dependency interface rather than concrete implementation, making it easier to independently modify and expand components; 3. Improve reusability and configuration flexibility. The same class can achieve diversified behavior by injecting different dependencies in different contexts, such as the development, production and testing environments using different logging methods. In addition, modern PHP frameworks such as Symfony and Laravel built-in DI containers further simplify the implementation of object management and dependency injection.

Course 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.

Course Introduction：Core points Drupal 8's ConfigFormBase class provides additional functionality to interact with the configuration system, allowing tools to convert forms to stored values. This can be done by replacing the extension class with ConfigFormBase and making the necessary changes in the form. The configuration in Drupal 8 is stored in a YAML file and can be changed through the UI for deployment across different sites. The service container in Drupal 8 allows the creation of a service, that is, a PHP class that performs global operations, and registers it into the service container for access. Dependency injection is used to pass objects to other objects, ensuring decoupling. You can create de in the root directory of the module

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
