How can normalization of data models in PHP applications help avoid errors and improve efficiency?

Normalization of data models in PHP applications helps avoid errors and improve efficiency by organizing data into separate tables with relationships, reducing data redundancy, and ensuring data integrity. This approach makes it easier to maintain and update the database structure, improves query performance, and prevents inconsistencies in the data. 

// Example of normalizing data models in PHP using PDO
try {
    $pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    
    // Create tables with relationships
    $pdo->exec("CREATE TABLE users (
        id INT PRIMARY KEY,
        name VARCHAR(50),
        email VARCHAR(50)
    )");
    
    $pdo->exec("CREATE TABLE posts (
        id INT PRIMARY KEY,
        title VARCHAR(50),
        content TEXT,
        user_id INT,
        FOREIGN KEY (user_id) REFERENCES users(id)
    )");
    
    // Insert data into tables
    $pdo->exec("INSERT INTO users (id, name, email) VALUES (1, 'John Doe', 'john@example.com')");
    $pdo->exec("INSERT INTO posts (id, title, content, user_id) VALUES (1, 'Hello World', 'This is a test post.', 1)");
    
    echo "Data models normalized successfully!";
} catch(PDOException $e) {
    echo "Error: " . $e->getMessage();
}
