php switch

Question

why the output here is "Working day" in this code :

$day = 'Wed';
switch ($day) {
case 'Mon':
echo 'First day of the week';
break;
case 'Tue':
case 'Wed':
case 'Thu':
echo 'Working day';
break;
case 'Fri':
echo 'Friday!';
break;
default:
echo 'Weekend!';
}

shouldn't here print the default ? because in case "wed" there is nothing ?

Answer 1

In a switch statement, you can have multiple cases for a single section of code. In this one, "Working Day" prints for "Tue", "Wed", and "Thu" cases.

The only way for a case to do nothing is to only have break; beneath it.
