💡 Hint

Common Mistakes

Using 'else' instead of 'default' in switch.

Forgetting to add a colon after the case or default.

The default case runs when no other case matches.

<?php
$color = 'yellow';
switch ($color) {
    case 'red':
        echo 'Stop';
        break;
    case 'yellow':

💡 Hint

Common Mistakes

Using 'continue' which is for loops, not switch.

Forgetting to add any statement to stop fall-through.

The break statement stops the switch from continuing to the next cases.

4fill in blank

hard

Fill both blanks to create a switch that prints 'Weekend' for 'Saturday' and 'Sunday', and 'Weekday' otherwise.

PHP

<?php
$day = 'Sunday';
switch([1]) {
    case 'Saturday':
    case [2]:
        echo 'Weekend';
        break;
    default:
        echo 'Weekday';
}
?>

Drag options to blanks, or click blank then click option'

A$day

B'Sunday'

💡 Hint

Common Mistakes

Using the variable name without the dollar sign.

Using the variable instead of the string for the second case.

The switch uses $day to check the day. The second case must be the string 'Sunday' to group weekend days.

5fill in blank

hard

Fill all three blanks to create a switch that prints 'Low', 'Medium', or 'High' based on the $level variable.

PHP

<?php
$level = 2;
switch([1]) {
    case 1:
        echo [2];
        break;
    case 2:
        echo [3];
        break;
    default:
        echo 'High';
}
?>

Drag options to blanks, or click blank then click option'

A$level

B'Low'

C'Medium'

💡 Hint

Common Mistakes

Not quoting the strings in echo.

Using the wrong variable name in the switch.

The switch checks the variable $level. For case 1, it prints 'Low'. For case 2, it prints 'Medium'. Otherwise, it prints 'High'.
