How can I use a switch statement with multiple cases in PHP? Example code:

$day = "Monday";

switch ($day) {
    case "Monday":
    case "Tuesday":
    case "Wednesday":
    case "Thursday":
    case "Friday":
        echo "It's a weekday";
        break;
    case "Saturday":
    case "Sunday":
        echo "It's a weekend";
        break;
    default:
        echo "Invalid day";
}
