How can PHP developers future-proof their code to avoid issues like the Year 2038 problem when working with dates and times?

The Year 2038 problem is a programming issue where systems using a 32-bit signed integer to store time values will encounter a limitation on January 19, 2038, when the value will overflow and cause errors. To future-proof PHP code, developers can use the DateTime class which supports 64-bit timestamps, allowing dates beyond 2038 to be handled correctly. 

// Create a 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');
