How can the use of additional tables improve the efficiency and organization of data in PHP applications?

To improve the efficiency and organization of data in PHP applications, additional tables can be used to store related data separately. This allows for better data normalization, reduces data redundancy, and makes it easier to retrieve and manipulate data when needed. 

// Example code snippet showing how additional tables can be used in PHP applications

// Create a new table to store user information separately
CREATE TABLE users (
    id INT AUTO_INCREMENT PRIMARY KEY,
    username VARCHAR(50) NOT NULL,
    email VARCHAR(100) NOT NULL,
    password VARCHAR(255) NOT NULL
);

// Create a new table to store user posts separately
CREATE TABLE posts (
    id INT AUTO_INCREMENT PRIMARY KEY,
    user_id INT,
    title VARCHAR(100) NOT NULL,
    content TEXT,
    FOREIGN KEY (user_id) REFERENCES users(id)
);
