Course Introduction：To modify the session saving path of PHP, there are two methods: 1. Modify session.save_path in php.ini to implement global settings; 2. Use session_save_path() to set dynamically in the code. The first method requires editing the php.ini file, finding and modifying session.save_path to the specified directory, restarting the server after saving, and ensuring that the directory exists and has read and write permissions; the second method is suitable for a single application, using session_save_path() to set the absolute path before calling session_start(), which does not affect other projects. Notes include: Make sure the path is correct and readable

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.
