What are the advantages of using DateTime objects in PHP for date manipulation compared to traditional methods?

When manipulating dates in PHP, using DateTime objects provides several advantages over traditional methods such as the date() function. DateTime objects offer more flexibility, better readability, and easier manipulation of dates, including arithmetic operations and timezone adjustments.

// Using DateTime objects for date manipulation
$date = new DateTime('2022-01-01');
$date->modify('+1 day');
echo $date->format('Y-m-d'); // Output: 2022-01-02
