// The splat operator (also known as the variadic operator) in PHP is represented by three dots (...) 
// It allows you to pass an arbitrary number of arguments to a function or method.

// Here's an example of using the splat operator in PHP:

function addNumbers(...$numbers) {
    $sum = 0;
    foreach ($numbers as $number) {
        $sum += $number;

// Named arguments were introduced in PHP 8, 
// and they allow you to pass arguments to a function or method by specifying the name of the argument 
// rather than relying on the order in which the arguments are defined.

// Here's an example of using named arguments in PHP:

function createUser($name, $email, $age) {
    echo "Name: $name <br>";
