Course Introduction：The method of getting the day of the week in PHP is as follows: 1. Use the date() function to match the 'w' or 'l' parameters to get the current week in the form of a number or English name respectively; 2. Convert it to Chinese week through a custom mapping array; 3. Use strtotime() to get the week of the specified date; 4. Pay attention to setting the time zone to ensure the accuracy of the results. For example, date('w') returns 0~6 to mean Sunday to Saturday, date('l') returns the complete English week name, and can output Chinese weekdays with a mapping array. When processing non-current dates, you need to use strtotime() to convert it to a timestamp and then pass it in date(). If the result is abnormal, check and set the correct time zone such as Asia/Shanghai.

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.
