Course Introduction：Composer.json's autoload configuration is used to automatically load PHP classes, avoiding manual inclusion of files. Use the PSR-4 standard to map the namespace to a directory, such as "App\":"src/" means that the class under the App namespace is located in the src/ directory; classmap is used to scan specific directories to generate class maps, suitable for legacy code without namespace; files are used to load a specified file each time, suitable for function or constant definition files; after modifying the configuration, you need to run composerdump-autoload to generate an automatic loader, which can be used in the production environment --optimize or --classmap-

Course Introduction：PHP's automatic loading methods include PSR-0, PSR-4, classmap and files. The core purpose is to implement automatic loading of classes without manually introducing files. 1. PSR-0 is an early standard, and automatically loads through class name and file path mapping, but because the naming specifications are strict and the support for underscores as directory separators have been rarely used; 2. PSR-4 is a modern standard, which adopts a more concise namespace and directory mapping method, allowing a namespace to correspond to multiple directories and does not support underscore separation, becoming the mainstream choice; 3. classmap generates a static mapping table of class names and paths by scanning the specified directory, which is suitable for legacy code that does not follow the PSR specification, but new files need to be regenerated and large directories

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.

By its design, Go is intended to provide a method for constructing system software on multi-core machines.
