Control Flow: Switch 4/6
Multiple Cases. Falling Through!
You sometimes want to make multiple expressions, all of which have the same result. Consider the following
if statement:if ($i == 1 ||
$i == 2 ||
$i == 3) {
echo '$i is somewhere between 1 and 3.';
}
With a
switch statement, you can do this by adding cases right after another without a break. This is called falling through. The following code works exactly like the aboveif statement:case 1:
case 2:
case 3:
echo '$i is somewhere between 1 and 3.';
break;
Instructions
Replace the two underscores to make the switch also check for 3 and 4.

<body>
<?php
$i = 5;
switch ($i) {
case 0:
echo '$i is 0.';
break;
case 1:
case 2:
case 3:
case 4:
case 5:
echo '$i is somewhere between 1 and 5.';
break;
case 6:
case 7:
echo '$i is either 6 or 7.';
break;
default:
echo "I don't know how much \$i is.";
}
?>
