How can default cases be utilized in a switch statement for style changes in PHP?

When using a switch statement for style changes in PHP, you can utilize a default case to handle any unexpected or unhandled cases. This can be useful for setting a default style if none of the specified cases match the input. By including a default case, you ensure that there is always a fallback option in case the input does not match any of the defined cases.

$style = "default";

switch ($userInput) {
    case "case1":
        $style = "style1";
        break;
    case "case2":
        $style = "style2";
        break;
    default:
        $style = "default";
        break;
}

echo "Selected style: " . $style;
