In what scenarios would using switch() statements be more elegant and efficient compared to nested if-else conditions in PHP?

Switch statements are more elegant and efficient than nested if-else conditions when you have multiple conditions to check against a single variable. Using switch() can make the code more readable and maintainable, especially when dealing with a large number of cases. It can also improve performance as switch statements are optimized by the PHP engine. 

// Using switch statement to handle multiple conditions
$day = "Monday";

switch ($day) {
    case "Monday":
        echo "Today is Monday";
        break;
    case "Tuesday":
        echo "Today is Tuesday";
        break;
    case "Wednesday":
        echo "Today is Wednesday";
        break;
    default:
        echo "Today is not a weekday";
}
