php function vs method in a class
Article Introduction：function is an independent function, suitable for general functions; method is part of the class, suitable for encapsulating object behavior. Function can be called directly, with global scope, cannot access class attributes, does not support object-oriented features, and is suitable for small scripts; method needs to be called through objects or classes, belongs to the class, can access private attributes, supports inheritance polymorphism, and is suitable for large project structures. Function or method should be used according to whether the status and encapsulation are required.

Python class method vs static method
Article Introduction：The main difference between classmethod and staticmethod is parameter passing and purpose. ① Classmethod receives the class as the first parameter (cls), which can be used to access class properties and methods, which are suitable for factory methods or class-level operations; ② Staticmethod does not receive automatically passed parameters, but is more like an ordinary function bound to a class, suitable for tool functions or logical encapsulation; ③ Classmethod supports inheritance and rewrite and can return subclass instances, and although staticmethod also supports rewrite, it does not involve class or instance state; ④ If the method needs to call the class itself data, select classmethod. If it is only logical classification and has no class structure, select staticme

What are traits in PHP, and how do they address limitations of single inheritance?
Article Introduction：PHP supports single inheritance, but trait can reuse methods from multiple sources. Trait is a code block containing reusable methods and can be introduced into the class to avoid the problem of multiple inheritance. For example, after defining Loggertrait and being used by the User class, the User class can use the log method. Trait is not an independent class, has no attributes and does not have "is-a" relationship. The way trait solves the single inheritance limit is to allow a class to use multiple traits at the same time, such as DatabaseTrait and LoggerTrait, thereby combining functions. When multiple traits have the same name method, you can specify which method to use insteadof, or use as a method to alias the method to distinguish calls.

What is the use of the << operator in PHP?
Article Introduction：In PHP, implementing polymorphism can be achieved through method rewriting, interfaces, and type prompts. 1) Method rewriting: Subclasses override parent class methods and perform different behaviors according to object type. 2) Interface: The class implements multiple interfaces to realize polymorphism. 3) Type prompt: Ensure that the function parameters are specific to the type and achieve polymorphism.
