Course Introduction：Select logging method: In the early stage, you can use the built-in error_log() for PHP. After the project is expanded, be sure to switch to mature libraries such as Monolog, support multiple handlers and log levels, and ensure that the log contains timestamps, levels, file line numbers and error details; 2.

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.
