What are the potential pitfalls or errors that can occur when using the switch function in PHP?

One potential pitfall when using the switch function in PHP is forgetting to include a break statement at the end of each case. This can lead to unintended fall-through behavior where multiple case blocks are executed. To avoid this, always remember to include a break statement after each case block to ensure that only the intended block is executed. 

$day = "Monday";

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