How can the use of function parameters improve the readability and maintainability of PHP code, as suggested in the forum discussion?

Using function parameters in PHP can improve the readability and maintainability of code by clearly defining the inputs required by a function and reducing the reliance on global variables. By passing parameters to functions, it becomes easier to understand the purpose of the function and how it interacts with other parts of the code. Additionally, function parameters make it easier to reuse functions in different contexts without having to modify the function itself. 

// Example of using function parameters to improve readability and maintainability

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

$total = calculateTotal(10, 5);
echo "Total: $total";
