How to create a class in C
Article Introduction：To create a C class, you need to use the class keyword to define the class name and member; 1. Use the class keyword followed by the class name and surrounded by curly braces; 2. Declare private data members and public member functions in the class; 3. Initialize the object with a constructor; 4. Provide an external access interface through the public access character; 5. Create an object and call its member functions to complete the operation; the complete class definition ends with a semicolon, and should follow the encapsulation principle, set the data members to private, and access it through the public method, so as to realize data hiding and modular design.

Demystifying foreach Behavior with Public vs. Private Object Properties
Article Introduction：Foreach only accesses public attributes when traversing objects in PHP; 2. Protected and private attributes are not visible, even if you use foreach($thisas...) inside the class; 3. To customize the traversal behavior, you can implement the Iterator or IteratorAggregate interface; 4. To check the properties that include private and protected, you need to use the Reflection class; 5.get_object_vars() also only returns the public attributes under the current scope. Therefore, foreach's behavior is the embodiment of PHP encapsulation characteristics, and non-public attributes will not be traversed.

Fun with Array Interfaces
Article Introduction：Key Points
PHP's array interface allows programmers to simulate the characteristics of native data types in custom classes, similar to Python's methods. This enables custom classes to work like arrays and allows common array operations such as counting elements, looping through elements, and accessing elements through indexes.
An interface is like a contract for a class, specifying the methods that a class must contain. They allow encapsulation of implementation details and provide syntax sugar, thereby improving the readability and maintainability of the code. PHP provides a library of predefined interfaces that can implement these interfaces to make objects similar to arrays.
Countable, ArrayAccess and Iterator interfaces in PHP allow objects to pass cou respectively

How to create a custom session handler in PHP?
Article Introduction：In PHP, custom session processing mechanism requires implementing the SessionHandlerInterface interface and registering handler. 1. Implement six core methods: open(), close(), read(), write(), destroy() and gc() to complete the session storage logic; 2. Create a custom handler class instance and register it through session_set_save_handler(); 3. Call session_start() before use to start the session. Suitable for improving performance, centralized management and extension functions. It is recommended to pay attention to permission control, concurrency problems and security protection to ensure the correct operation of GC and ensure the sess
