What are the advantages of using DateTime objects in PHP for date and time manipulation over traditional functions like date() and time()?

When working with dates and times in PHP, using DateTime objects provides a more object-oriented approach to date and time manipulation compared to traditional functions like date() and time(). DateTime objects offer more flexibility, better readability, and easier handling of time zones and daylight saving time adjustments.

// Using DateTime objects for date and time manipulation
$date = new DateTime();
echo $date->format('Y-m-d H:i:s');
