What potential pitfalls should beginners be aware of when using Modulo in PHP for controlling output formatting?

Beginners should be aware that using Modulo in PHP for controlling output formatting can lead to unexpected results if not used correctly. One common pitfall is forgetting to account for the zero-based indexing when using Modulo, which can result in off-by-one errors in the output. To avoid this issue, beginners should always remember to adjust their Modulo calculations accordingly. 

// Example of adjusting Modulo calculations for zero-based indexing
$numbers = [1, 2, 3, 4, 5];

foreach ($numbers as $index => $number) {
    if ($index % 2 == 0) {
        echo "Even number: $number\n";
    } else {
        echo "Odd number: $number\n";
    }
}
