What is inheritance in PHP object-oriented programming?
Article Introduction：Inheritance in PHP object-oriented programming means that one class (subclass) can inherit the properties and methods of another class (parent class) to implement code reuse and clearer structure. 1. Create subclasses using extends keyword; 2. Subclasses can call parent class methods and modify their behavior through rewriting; 3. Applicable to "is-a" relationships to avoid deep inheritance hierarchy and tight coupling. For example, the Dog class inherits the Animal class and overrides the speak() method, which can both reuse code and customize functions.

Collection Classes in PHP
Article Introduction：Core points
PHP collection class is an object-oriented alternative to traditional array data structures, providing a structured way to manage object groups and providing built-in data manipulation methods.
The basic collection class should provide methods for adding, retrieving, and deleting items, as well as methods for determining whether the collection size and given keys exist in the collection.
Collection classes can improve performance, especially when working with large datasets, because they use delayed instantiation, creating elements in the array only when needed, saving system resources.
Collection classes are especially useful when working with databases using PHP, because they can manage large datasets more efficiently and make the code easier to read and maintain.
Collection classes are object-oriented alternatives to traditional array data structures. Similar to arrays,

python sqlalchemy orm example
Article Introduction：First, install SQLAlchemy and use its ORM to define the model, create tables, insert and query data: 1. Define the User model and create the SQLite database and table structure; 2. Create a session and add a single or multiple user data and submit it; 3. Use the query method to query all, conditions, scope and fuzzy matching users; 4. Update data by modifying object properties or calling the update method; 5. Use the delete method to delete the specified user; 6. Close the session after the operation is completed; finally submit the changes through session.commit(), and the entire process realizes the database addition, deletion, modification and query operations, and can be adapted to MySQL or PostgreSQL to simplify database operations in an object-oriented manner.

What is C and what is it used for?
Article Introduction：C is a statically typed, compiled, and general programming language that supports procedural, object-oriented and generic programming. The design goal is to provide high performance and control over hardware. It originated in the C language, extends features such as classes, objects, exception handling, and at the same time retains the efficiency of C. C is mainly used in game development (such as UnrealEngine), system and embedded development (operating system, database), high-performance computing (financial transactions, image processing) and tool development (compiler). Learning suggestions include: 1. Master the basics of C language first; 2. Learn object-oriented features; 3. Be familiar with the STL standard library; 4. Understand advanced features such as RAII and smart pointers; 5. Start practicing with a simple project.

How do I connect to a database using PHP (MySQLi, PDO)?
Article Introduction：To connect to a database, there are two ways to PHP: MySQLi and PDO. 1.MySQLi is simple and direct, suitable for projects that only use MySQL, supports process-oriented and object-oriented writing, and it is recommended to use object methods to obtain a clearer structure; 2.PDO is more flexible and supports multiple databases, suitable for projects that may migrate databases or require unified interfaces, has preprocessing statements to prevent SQL injection, and provides a unified error handling mechanism. Choosing MySQLi allows for a cleaner API and slightly higher performance, while choosing PDO allows for improved scalability and security. Both need to pay attention to correct configuration, error handling and connection closure.
