How can normalizing data in a database help improve the efficiency and readability of PHP code?

Normalizing data in a database helps improve the efficiency and readability of PHP code by reducing redundancy and ensuring data consistency. By organizing data into separate tables and establishing relationships between them, queries become simpler and more efficient. This also makes it easier to update and maintain the database structure, leading to cleaner and more understandable PHP code. 

// Example of querying normalized data in a database
$query = "SELECT users.name, orders.order_date, products.product_name 
          FROM users 
          JOIN orders ON users.id = orders.user_id 
          JOIN order_details ON orders.id = order_details.order_id 
          JOIN products ON order_details.product_id = products.id";
$result = mysqli_query($connection, $query);

while($row = mysqli_fetch_assoc($result)) {
    echo "User: " . $row['name'] . " | Order Date: " . $row['order_date'] . " | Product: " . $row['product_name'] . "<br>";
}
