Course 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.

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：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.
