What are the potential pitfalls of misinterpreting the DateInterval documentation in PHP?

Misinterpreting the DateInterval documentation in PHP can lead to incorrect usage of the class methods, resulting in unexpected behavior or errors in your code. To avoid this, make sure to carefully read the documentation and understand how to properly create and manipulate DateInterval objects. 

// Incorrect usage of DateInterval
$interval = new DateInterval('P1D');
echo $interval->format('%d'); // This will not output the number of days

// Correct way to create and format DateInterval
$interval = new DateInterval('P1D');
$now = new DateTime();
$now->add($interval);
echo $now->format('Y-m-d');
