In what scenarios should the DateTime class be preferred over strtotime() for date conversions in PHP?

The DateTime class should be preferred over strtotime() for date conversions in PHP when you need more control and flexibility over date manipulation, formatting, and time zones. DateTime provides a more object-oriented approach to working with dates and times, allowing for easier handling of date calculations and comparisons.

// Example of using DateTime class for date conversions
$dateString = '2022-12-31';
$date = new DateTime($dateString);
echo $date->format('Y-m-d'); // Output: 2022-12-31
