How can normalization of database tables improve sorting and querying efficiency in PHP applications?

Normalization of database tables can improve sorting and querying efficiency in PHP applications by reducing data redundancy and ensuring data integrity. This allows for more efficient storage and retrieval of data, as well as faster query processing. By breaking down data into smaller, more manageable tables and establishing relationships between them, normalization can help optimize database performance.

// Example code snippet demonstrating normalization of database tables in PHP

// Create a users table
CREATE TABLE users (
    id INT PRIMARY KEY,
    username VARCHAR(50) UNIQUE,
    email VARCHAR(100) UNIQUE,
    password VARCHAR(255)
);

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