How can PHP DateTime class help in avoiding the 2038-year problem?

The 2038-year problem, also known as the Year 2038 problem or Y2K38, is a programming issue where systems using a 32-bit signed integer for Unix timestamps will overflow on January 19, 2038. To avoid this problem, developers can use the PHP DateTime class, which supports dates beyond 2038 and provides a more robust solution for handling dates and times.

// Create a new DateTime object with a date beyond 2038
$date = new DateTime('2040-01-01');

// Format the date as a string
echo $date->format('Y-m-d');
