Are there any potential pitfalls or drawbacks to combining a CASE field with a DEFAULT field in a PHP switch() statement?

Combining a CASE field with a DEFAULT field in a PHP switch() statement may lead to unexpected behavior or errors if not handled correctly. To avoid potential pitfalls, make sure that the DEFAULT case is placed at the end of the switch statement and that it includes a break statement to prevent fall-through to other cases. 

switch ($variable) {
    case 'value1':
        // do something
        break;
    case 'value2':
        // do something else
        break;
    default:
        // handle default case
        break;
}
