How can one avoid the 1970 and 2038 problem when working with dates in PHP?

The 1970 problem refers to the limitation of Unix timestamps in PHP, which start from January 1, 1970, and may overflow in 2038. To avoid this issue, use PHP's DateTime class which supports a wider range of dates. By using DateTime, you can work with dates beyond 2038 without encountering the overflow problem.

$date = new DateTime('2050-01-01');
echo $date->format('Y-m-d');
