Automatically load global auxiliary files through Composer's autoload to ensure convenient access; 4. Use namespace and folder structure to manage a large number of auxiliary classes, such as class files divided by functions under App\Helpers. These methods are selected according to the project size. Small projects can use a single file, while large projects are suitable for using structured classes under namespace.

Course Introduction：Comments are crucial in PHP development, and reasonable comments can improve code readability and maintenance. When choosing annotation method, 1. Single-line comments (// or #) are suitable for explaining single-line code or temporary blocking code; 2. Multi-line comments (/.../) are suitable for explaining function, class or file header information, but nested use should be avoided. 3. It is recommended to write DocBlock comments for functions and classes to clarify the purpose, parameters and return values to support IDE prompts and document generation. 4. Comments need to be modified synchronously as the code is updated to delete useless comments to prevent misleading. 5. Complex logic should be explained "why" rather than just describing operations. 6. The comments should be concise and clear, avoid lengthy and nonsense, and it is recommended to use Chinese writing. Although good annotation habits are small, they can significantly improve the quality of the code

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.
