What are some common pitfalls when trying to manipulate dates in PHP, especially when trying to subtract or add days to a given date?

When manipulating dates in PHP, a common pitfall is not taking into account leap years or daylight saving time changes, which can lead to inaccurate calculations. To avoid this, it's recommended to use PHP's built-in DateTime class, which handles these complexities for you. Additionally, make sure to use the correct format when adding or subtracting days to a date to ensure accurate results. 

$date = new DateTime('2022-03-15');
$date->modify('+3 days');
echo $date->format('Y-m-d');
