Is it necessary to include break statements in empty case blocks in a PHP switch statement?

It is not necessary to include break statements in empty case blocks in a PHP switch statement. The break statement is used to exit the switch statement and prevent fall-through to the next case. If a case block is empty, there is no code to execute, so there is no need for a break statement.

$fruit = "apple";

switch ($fruit) {
    case "apple":
        // code for apple
        break;
    case "banana":
        // code for banana
        break;
    case "orange":
        // code for orange
        break;
    default:
        // default code
        break;
}
