for ($i = 0; $i < 3; $i++) {
    for ($j = 0; $j < 3; $j++) {
        if ($j == 1) {
            [1];
        }
        echo "$i$j ";
    }
    echo "\n";

medium

Complete the code to break out of both loops when $j equals 1.

PHP

<?php
for ($i = 0; $i < 3; $i++) {
    for ($j = 0; $j < 3; $j++) {
        if ($j == 1) {
            [1];
        }
        echo "$i$j ";
    }
    echo "\n";
}

💡 Hint

Common Mistakes

Using break without a number only exits the inner loop.

The break 2 statement breaks out of two nested loops.

3fill in blank

hard

Fix the error in the break statement to exit three nested loops.

PHP

<?php
for ($a = 0; $a < 2; $a++) {
    for ($b = 0; $b < 2; $b++) {
        for ($c = 0; $c < 2; $c++) {
            if ($c == 1) {
                [1];
            }
            echo "$a$b$c ";
        }
    }
    echo "\n";
}
?>

💡 Hint

Common Mistakes

Using break 2 only exits two loops, not three.

To break out of three nested loops, use break 3.

4fill in blank

hard

Fill both blanks to break out of the correct number of loops and print the last value of $i.

PHP

<?php
for ($i = 0; $i < 5; $i++) {
    for ($j = 0; $j < 5; $j++) {
        if ($j == 2) {
            [1];
        }
    }
}
echo $[2];
?>

💡 Hint

Common Mistakes

Using break without a number exits only the inner loop.

Printing $j instead of $i after the loops.

break 2 exits both loops when $j equals 2, then echo $i; prints the current value of $i.

5fill in blank

hard

Fill all three blanks to break out of the correct loops and print the sum of $x and $y.

PHP

<?php
for ($x = 0; $x < 4; $x++) {
    for ($y = 0; $y < 4; $y++) {
        if ($y == 3) {
            [1];
        }
        echo "$x$y ";
    }
}
echo [2] + [3];
?>

💡 Hint

Common Mistakes

Using break without a number exits only the inner loop.

Mixing up which variables to print.

break 2 exits both loops when $y equals 3, then echo $x + $y; prints their sum.
