Differences Between Static Method and Class Method in Python
Article Introduction：The main differences between @staticmethod and @classmethod are parameter passing, usage scenarios and inheritance performance. 1. In parameter passing, the static method does not automatically pass any implicit parameters, while the class method automatically receives the class object as the first parameter (cls). 2. In terms of usage scenarios, static methods are suitable for tool functions that are independent of classes and instances. Class methods are suitable for factory methods or situations where class state needs to be accessed/modified. 3. In inheritance, the static method is still bound to the class at the time of definition when invoking, and the class method will be automatically bound to the subclass that calls it. When selecting, you should decide which decorator to use based on whether the class or instance is needed and whether it is used to create the instance.

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

What is inheritance in PHP object-oriented programming?
Article Introduction：Inheritance in PHP object-oriented programming means that one class (subclass) can inherit the properties and methods of another class (parent class) to implement code reuse and clearer structure. 1. Create subclasses using extends keyword; 2. Subclasses can call parent class methods and modify their behavior through rewriting; 3. Applicable to "is-a" relationships to avoid deep inheritance hierarchy and tight coupling. For example, the Dog class inherits the Animal class and overrides the speak() method, which can both reuse code and customize functions.
