- Example of using Late Static Binding in PHP.
- 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

- The Importance of Writing Meaningful Code and Documentation
- Many developers believe that the first priority is to understand the requirements and write code quickly. However, this view is flawed. One of the responsibilities of a developer is to write appropriate documentation, but this is often misunderstood or poorly implemented. Some developers write so verbosely that the core requirements or business logic are obscured - this is like killing a chicken with a bull's-eye. Writing documentation line by line does not automatically make the code easier to read. Documentation should focus only on necessary information, especially when explaining key project requirements or business logic. But this doesn't mean that documentation can be completely ignored for simple cases; on the contrary, well-written, self-explanatory code can often reduce the need for excessive documentation. The balance between code and documentation A common scenario is to use a database table to check if data exists or
