What are the potential pitfalls of using date("m") to determine the current month in PHP?

Using date("m") to determine the current month in PHP may return a two-digit representation of the month (e.g., "01" for January), which could lead to potential issues when comparing or manipulating the month as a numeric value. To avoid this pitfall, it is recommended to use the "n" format character instead, which returns the month without leading zeros (e.g., "1" for January).

$currentMonth = date("n");
echo $currentMonth;
