In what situations would it be more beneficial to keep related data in separate tables in PHP development?

In PHP development, it may be more beneficial to keep related data in separate tables when dealing with complex data structures or when following database normalization principles. By separating related data into different tables, you can reduce redundancy, improve data integrity, and make it easier to manage and query the database. 

// Example of keeping related data in separate tables in PHP development

// Create a users table
CREATE TABLE users (
    id INT PRIMARY KEY,
    username VARCHAR(50),
    email VARCHAR(50)
);

// Create a posts table
CREATE TABLE posts (
    id INT PRIMARY KEY,
    user_id INT,
    title VARCHAR(100),
    content TEXT,
    FOREIGN KEY (user_id) REFERENCES users(id)
);
