What are the best practices for normalizing database structures and optimizing data organization for efficient PHP application development in a limited hosting environment?

To optimize data organization in a limited hosting environment for efficient PHP application development, it is essential to normalize the database structures. This involves breaking down data into smaller, related tables to reduce redundancy and improve data integrity. Additionally, using indexing, proper data types, and efficient queries can further enhance performance.

// Example code snippet for normalizing database structures in PHP

// Create a new table for storing user information
CREATE TABLE users (
    id INT PRIMARY KEY,
    username VARCHAR(50) UNIQUE,
    email VARCHAR(100) UNIQUE
);

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