How can normalization principles be applied to improve the structure and efficiency of PHP scripts?

To improve the structure and efficiency of PHP scripts, normalization principles can be applied by breaking down complex logic into smaller, reusable components. This can involve separating concerns, reducing redundancy, and adhering to best practices like DRY (Don't Repeat Yourself) and SRP (Single Responsibility Principle). By organizing code in a normalized way, it becomes easier to maintain, scale, and debug.

// Example of applying normalization principles to improve PHP script structure

// Separate concerns by creating functions for specific tasks
function calculateTotal($price, $quantity) {
    return $price * $quantity;
}

function displayTotal($total) {
    echo "Total: $" . $total;
}

// Reduce redundancy by reusing functions
$price = 10;
$quantity = 5;

$total = calculateTotal($price, $quantity);
displayTotal($total);
