What are the best practices for designing PHP functions to ensure they are versatile and reusable for different operations?

To ensure PHP functions are versatile and reusable for different operations, it is important to follow best practices such as using clear and descriptive function names, keeping functions focused on a single task, using parameters to make functions adaptable, and returning values instead of echoing output.

function calculateTotal($price, $quantity) {
    return $price * $quantity;
