Are there any potential pitfalls in using strptime and strtotime functions for date manipulation in PHP?

One potential pitfall in using strptime and strtotime functions for date manipulation in PHP is that they may not handle all date formats consistently, leading to unexpected results. To mitigate this issue, it's recommended to use the DateTime class, which provides more robust date manipulation capabilities and better support for different date formats.

$dateString = '2022-12-31';
$dateTime = DateTime::createFromFormat('Y-m-d', $dateString);
echo $dateTime->format('Y-m-d');
