Example of using Late Static Binding in PHP.
Article 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

What is late static binding in PHP, and how does it differ from self::?
Article Introduction：In PHP, latestatic binding solves the limitations of self:: in inheritance through the static:: keyword. When using self::, it always points to the class that defines the method, not to call or inherit it; while static:: determines the target class at runtime, thus correctly referring to the subclass that is actually called. For example, if a method defined in the parent class is called by a subclass, self::class returns the parent class name, and static::class returns the child class name. 1. Use self:: to strictly refer to the current class definition; 2. Use static:: to support inheritance and allow subclass rewriting behavior; 3. Common application scenarios include factory mode
