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).

What are some common use cases for Redis in a PHP application (e.g., caching, session handling)?
Article Introduction：Redis has four main core uses in PHP applications: 1. Cache frequently accessed data, such as query results, HTML fragments, etc., and control the update frequency through TTL; 2. Centrally store session information to solve the problem of session inconsistency in multi-server environments. The configuration method is to set session.save_handler and session.save_path in php.ini; 3. Implement current limiting and temporary counting, such as limiting the number of login attempts per hour, and using keys with expiration time for efficient counting; 4. Build a basic message queue, and implement asynchronous task processing through RPUSH and BLPOP operations, such as email sending or image processing, thereby improving system response speed and expansion

Understanding JavaScript's Event Loop Mechanism and its Differences from Java's Event Handling
Article Introduction：The event loop of JavaScript is a single-threaded asynchronous processing mechanism, consisting of a call stack, a callback queue and an event loop, which is executed in order of priority between macro tasks and micro tasks; 1. The call stack records the current execution function; 2. The callback queue stores asynchronous callbacks; 3. The event loop continuously checks the call stack and pushes callback execution; Java's event processing is based on multi-threading and adopts a listening-trigger mode, and events are executed in special threads such as EDT; 1. User operations generate events; 2. Events are dispatched to listeners; 3. The callback method is executed synchronously in a specific thread; the key difference between the two is that JS relies on the event loop to execute tasks sequentially, while Java uses threads to implement parallel processing.
