In PHP:

Here you go:

 0);

    return $result;
}

function PrintArray($array)
{
    for ($i = 0; $i < count($array); $i++) {
        for ($j = 0; $j < count($array); $j++) {
            echo str_pad($array[$i][$j],3,' ');
        }
        echo '
';
    }
}

$arr = getSpiralArray(4);
echo '
';
PrintArray($arr);
echo '
';
?>
