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
