What are the differences between Interfaces and Abstract Classes in PHP?
Article Introduction：In PHP, the difference between interfaces and abstract classes is mainly reflected in the definition, inheritance model and implementation method. 1. The interface only defines method signatures (PHP8.1 supports default methods), emphasizing "what should be done", while abstract classes can contain abstract methods and concrete implementations, emphasizing "how to implement some functions". 2. Classes can implement multiple interfaces, but can only inherit one abstract class, so interfaces are more flexible when combining multiple behaviors. 3. The interface method is exposed by default and cannot have attributes. Abstract classes support arbitrary access control, attributes, constructors and destructors. 4. Use interfaces when a unified API is required or when an interchangeable component is designed; use abstract classes when a shared state or logically related classes. The selection basis is: the interface is used to define the contract, and the abstract class is used to share the implementation logic.

What are PSR Standards and Why Are They Important in PHP?
Article Introduction：PSR is a PHP standard recommendation, formulated by the PHP framework interoperability group, aiming to improve code consistency, readability and cross-frame compatibility. Common standards include: 1. Basic PSR-1 specifications, such as labels and naming conventions; 2. PSR-4 automatic loading standards, defining class and path mapping; 3. PSR-12 extended coding style, refined format rules; 4. PSR-3 log interface, supporting log library replacement; 5. PSR-7 HTTP message interface, convenient for middleware and API development. Its value is reflected in improving multi-project collaboration efficiency, enhancing tool support, simplifying integration, and improving code expertise. Application methods include using Composer to configure PSR-4, automatically format code with the help of tools, and manually following PSR

How does Laravel's service container use reflection for auto-wiring?
Article Introduction：Laravel's container uses the PHP reflection API to automatically parse class dependencies to achieve automatic assembly; 1. When requesting to parse a class, if the constructor parameter has a type prompt and can be parsed, it can be instantiated without explicit binding; 2. The container obtains constructor parameters through ReflectionClass, uses ReflectionParameter to read the type prompt and recursively parse each dependency; 3. Reliability is recursively parsed according to the graph, such as the OrderController relies on the OrderService, which relies on the OrderRepository, and finally builds layer by layer from the bottom layer; 4. If the parameter has no type prompt, is a basic type or has no binding to the interface, an exception is thrown unless provided

How to use PHP to build a payment system to monetize PHP payment interface docking process
Article Introduction：Choose a payment platform based on user portrait.

Registering a merchant account to obtain AppID, MCHID, API keys and other qualifications is the prerequisite; 3. Using the official PHPSDK integrated interface can simplify development and improve security; 4. The PHP backend generates orders and initiates prepayment requests, and the front end calls for payment based on the returned data; 5. Asynchronous callbacks are the final basis for successful payment, and signatures, IP whitelists, SSL encryption transmission must be verified and idempotence must be realized to prevent repeated processing; 6. Timeout orders are closed through timed tasks, refunds must be called to the API and handled multiple states, reconciliation needs to be regularly compared with the platform flow and system orders to ensure the consistency of funds, and the entire flow

How to update Laravel to the latest version?
Article Introduction：Upgrading Laravel to the latest version requires caution. 1. Check the difference between the current version and the target version, confirm the upgrade path and read the BreakingChanges in the official document; 2. Be sure to back up the code and database before upgrading, so that it can quickly roll back if errors occur; 3. Modify the Laravel version number in composer.json and check whether other dependencies are compatible; 4. Run composerupdate and deal with possible PHP version, extension or package conflict problems; 5. Clean up the Laravel cache and regenerate the optimization file to ensure that the new functions are running normally; 6. Test core functions such as login, database reading and writing, queue tasks, API interface and third-party service docking, and verify them by module.
