Continue statement with levels in PHP - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to skip the current iteration in the inner loop.

PHP

<?php
for ($i = 1; $i <= 3; $i++) {
    for ($j = 1; $j <= 3; $j++) {
        if ($j == 2) {
            [1];
        }
        echo "$i,$j\n";
    }
}
?>

💡 Hint

Common Mistakes

Using 'break' instead of 'continue' which exits the loop instead of skipping iteration.

The continue statement skips the current iteration of the loop it is in. Here, it skips when $j == 2 in the inner loop.

2fill in blank

medium

Complete the code to skip the current iteration of the outer loop using continue with level.

PHP

<?php
for ($i = 1; $i <= 3; $i++) {
    for ($j = 1; $j <= 3; $j++) {
        if ($j == 2) {
            [1] 2;
        }
        echo "$i,$j\n";
    }
}
?>

💡 Hint

Common Mistakes

Using 'break 2;' which exits the outer loop instead of continuing it.

The continue 2; statement skips the current iteration of the outer loop (two levels up).

3fill in blank

hard

Fix the error in the continue statement to skip the outer loop iteration.

PHP

<?php
for ($x = 1; $x <= 3; $x++) {
    for ($y = 1; $y <= 3; $y++) {
        if ($y == 3) {
            [1] 2;
        }
        echo "$x,$y\n";
    }
}
?>

Bcontinue;

💡 Hint

Common Mistakes

Including the semicolon inside the blank causing syntax error.

Using wrong level number.

The correct syntax is continue 2; without a semicolon inside the blank. The blank replaces only the keyword and level number together, so the blank must be 'continue'. The number 2 is already in the code after the blank.

4fill in blank

hard

Fill both blanks to skip the current iteration of the inner loop and continue the outer loop.

PHP

<?php
for ($a = 1; $a <= 3; $a++) {
    for ($b = 1; $b <= 3; $b++) {
        if ($b == 2) {
            [1];
            [2] 2;
        }
        echo "$a,$b\n";
    }
}
?>

💡 Hint

Common Mistakes

Using 'break' instead of 'continue' which changes loop behavior.

Mixing 'break' and 'continue' incorrectly.

First continue; skips the inner loop iteration. Then continue 2; skips the outer loop iteration. Both use 'continue' with and without level.

5fill in blank

hard

Fill all three blanks to skip the current iteration of the innermost loop, then the middle loop, then the outer loop.

PHP

<?php
for ($i = 1; $i <= 3; $i++) {
    for ($j = 1; $j <= 3; $j++) {
        for ($k = 1; $k <= 3; $k++) {
            if ($k == 2) {
                [1];
                [2] 2;
                [3] 3;
            }
            echo "$i,$j,$k\n";
        }
    }
}
?>

💡 Hint

Common Mistakes

Using 'break' or 'exit' which exit loops instead of continuing.

Omitting the level number for multi-level continue.

Each blank uses 'continue' to skip the current iteration at different loop levels: innermost (no level), middle (level 2), and outermost (level 3).
