Course Introduction：Delayed static binding in PHP: flexible database queries Lazy static binding (LSB) is a feature in PHP that allows a subclass to reference a static property or method of its parent class using the static keyword. This makes it possible to implement dynamic behavior in classes, which is especially useful in inheritance and subclass functionality customization. The core of delayed static binding lies in the use of the static keyword: when the PHP interpreter encounters the static attribute when compiling a function, it will delay determining its value until runtime. The value ultimately comes from the class that calls the function. Application scenario: dynamic database query Suppose you are developing a web application with a database. You have a Database base class that contains the methods for interacting with the database

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.
