PHP Interface vs Abstract Class:?When to use each.
Article Introduction：The article discusses the use of interfaces and abstract classes in PHP, focusing on when to use each. Interfaces define a contract without implementation, suitable for unrelated classes and multiple inheritance. Abstract classes provide common funct

A Crash Course of Changes to Exception Handling in PHP 7
Article Introduction：Major improvements in exception handling in PHP 7
PHP 7 has made significant improvements to exception handling, introducing the Throwable interface and the Error class, which significantly enhances error handling capabilities. The Throwable interface is the base interface of the Exception and Error classes, allowing developers to catch all throwable errors, whether exceptions or errors. The Error class handles various internal PHP errors, including fatal errors and type errors, and is broken down into four subclasses: ArithmeticError, TypeError, ParseError, and AssertionError.

Describe the differences between an Interface and an Abstract Class in php.
Article Introduction：Interfaces define behavioral specifications, and abstract classes provide partial implementations. The interface only defines methods but does not implement them (PHP8.0 can be implemented by default), supports multiple inheritance, and methods must be public; abstract classes can contain abstract and concrete methods, support single inheritance, and members can be protected or public. Interfaces are used to unify behavioral standards, realize polymorphism, and multiple inheritance; abstract classes are used to encapsulate public logic and share partial implementations. Selection basis: Use interfaces when you need to flexibly define behaviors, and use abstract classes when you need to share logic.

What is the difference between an abstract class and an interface in PHP?
Article Introduction：The main difference between an abstract class and an interface is that an abstract class can contain the implementation of a method, while an interface can only define the signature of a method. 1. Abstract class is defined using abstract keyword, which can contain abstract and concrete methods, suitable for providing default implementations and shared code. 2. The interface is defined using the interface keyword, which only contains method signatures, which is suitable for defining behavioral norms and multiple inheritance.

When would you use a trait versus an abstract class or interface in PHP?
Article Introduction：In PHP, trait is suitable for situations where method reuse is required but not suitable for inheritance. 1) Trait allows multiplexing methods in classes to avoid multiple inheritance complexity. 2) When using trait, you need to pay attention to method conflicts, which can be resolved through the alternative and as keywords. 3) Overuse of trait should be avoided and its single responsibility should be maintained to optimize performance and improve code maintainability.

What are interfaces in PHP?
Article Introduction：Interfaces are used in PHP to define contracts that classes must follow, specifying methods that classes must implement, but do not provide specific implementations. This ensures consistency between different classes and facilitates modular, loosely coupled code. 1. The interface is similar to a blueprint, which specifies what methods should be used for a class but does not involve internal logic. 2. The class that implements the interface must contain all methods in the interface, otherwise an error will be reported. 3. Interfaces facilitate structural consistency, decoupling, testability and team collaboration across unrelated classes. 4. Using an interface is divided into two steps: first define it and then implement it in the class. 5. Classes can implement multiple interfaces at the same time. 6. The interface can have constants but not attributes. PHP7.4 supports type attributes but is not declared in the interface. PHP8.0 supports named parameters to improve readability.

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.

How do abstract classes differ from interfaces in PHP, and when would you use each?
Article Introduction：Abstract classes and interfaces have their own uses in PHP. 1. Abstract classes are used to share code, support constructors and control access, and include abstract methods and concrete methods. 2. The interface is used to define behavior contracts. All methods must be implemented and are public by default, and support multiple inheritance. 3. Since PHP8, the interface can contain default methods to implement, but there is still no constructor or state. 4. When using abstract classes, you need to encapsulate implementation details; when using interfaces, you need to define cross-class behavior or build plug-in systems. 5. Can be used in combination: abstract classes implement interfaces or combine multiple interfaces into one abstract class. Select whether the structure plus sharing behavior (abstract class) or only the structure (interface).
