In what scenarios would creating a separate table for relationships between categories and articles be beneficial in PHP development?

Creating a separate table for relationships between categories and articles is beneficial in PHP development when you have a many-to-many relationship between categories and articles. This allows for more flexibility in managing the relationships and makes it easier to query and retrieve data related to specific categories or articles.

CREATE TABLE category_article (
    id INT AUTO_INCREMENT PRIMARY KEY,
    category_id INT,
    article_id INT,
    FOREIGN KEY (category_id) REFERENCES categories(id),
    FOREIGN KEY (article_id) REFERENCES articles(id)
);
