What are the potential issues with using two-digit years in PHP for date manipulation?

When using two-digit years in PHP for date manipulation, potential issues can arise when trying to calculate dates beyond the year 2038 due to the Year 2038 problem. To solve this issue, it is recommended to use four-digit years to ensure accurate date calculations and avoid any problems related to the Year 2038 bug. 

// Use four-digit years for accurate date calculations

$new_date = date('Y-m-d', strtotime($date));
echo $new_date;
