What is the "Year 2038 Problem" in PHP and how does it affect strtotime function on 64-bit systems?

The "Year 2038 Problem" in PHP is a limitation where the Unix timestamp will overflow on January 19, 2038, causing date-related functions like strtotime to potentially produce incorrect results. To solve this issue on 64-bit systems, you can use the DateTime class instead of strtotime to handle dates beyond 2038. 

$date = '2040-01-01';
$dateTime = DateTime::createFromFormat('Y-m-d', $date);
echo $dateTime->format('Y-m-d');
