What potential pitfalls should be considered when using strftime to convert a month number to a month name in PHP?

When using strftime to convert a month number to a month name in PHP, one potential pitfall to consider is that the month number should be in the range of 1 to 12 for the conversion to work correctly. If an invalid month number is provided, strftime may return unexpected results or throw an error. To avoid this issue, it is important to validate the month number before passing it to the strftime function. 

$monthNumber = 6;

if ($monthNumber >= 1 && $monthNumber <= 12) {
    $monthName = strftime('%B', mktime(0, 0, 0, $monthNumber, 1));
    echo $monthName;
} else {
    echo "Invalid month number";
}
