What are the best practices for normalizing data in a PHP application to avoid complications like those mentioned in the forum thread?

Issue: Normalizing data in a PHP application is essential to avoid complications such as data redundancy, inconsistency, and update anomalies. To ensure data integrity and efficiency, it is recommended to follow best practices like breaking down data into smaller tables, establishing relationships between tables using foreign keys, and avoiding repeating groups of data within a single table. PHP Code Snippet: 

// Create a normalized database structure with separate tables for related data

// Example: Users table
CREATE TABLE users (
    id INT PRIMARY KEY,
    username VARCHAR(50) UNIQUE
);

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

// Example: Comments table
CREATE TABLE comments (
    id INT PRIMARY KEY,
    post_id INT,
    user_id INT,
    content TEXT,
    FOREIGN KEY (post_id) REFERENCES posts(id),
    FOREIGN KEY (user_id) REFERENCES users(id)
);
