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.

PHP Master | Working with Slim Middleware
Article Introduction：Slim Framework Middleware: Building Powerful PHP Micro Applications
Slim is a powerful PHP mini framework, where middleware features allow implementation of various filter-style services such as authentication and caching in applications. Middleware encapsulates applications and can affect the application's environment as well as request and response objects.
Key points:
Slim's middleware is a powerful feature that allows the implementation of various filter-style services such as authentication and caching. Middleware encapsulates applications and can affect the application's environment, request and response objects.
To implement middleware in Slim, you need to write a class that extends the SlimMiddleware class and overrides the call() method. This method is
