Are there any common mistakes to avoid when using date_diff in PHP?

One common mistake to avoid when using date_diff in PHP is not passing DateTime objects as parameters. Date_diff requires two DateTime objects as arguments to calculate the difference between them. Make sure to create DateTime objects for the dates you want to compare before using date_diff. 

$date1 = new DateTime('2022-01-01');
$date2 = new DateTime('2022-01-10');

$interval = date_diff($date1, $date2);
echo $interval->format('%R%a days');
