What are the advantages and disadvantages of using switch-case statements versus other control structures in PHP for calculator applications?

Switch-case statements can be advantageous for calculator applications in PHP because they allow for easy organization of multiple conditions and provide a clear structure for handling different operations. However, switch-case statements can become cumbersome and less efficient when dealing with a large number of cases or complex conditions. In such cases, using other control structures like if-else statements or arrays may offer more flexibility and readability. 

$operator = '+'; // Example operator
$num1 = 10;
$num2 = 5;

switch($operator){
    case '+':
        $result = $num1 + $num2;
        break;
    case '-':
        $result = $num1 - $num2;
        break;
    case '*':
        $result = $num1 * $num2;
        break;
    case '/':
        $result = $num1 / $num2;
        break;
    default:
        $result = "Invalid operator";
}

echo "Result: " . $result;
