What are the advantages and disadvantages of using PHP's DateTime class to manipulate dates compared to traditional date functions?

When manipulating dates in PHP, using the DateTime class provides a more object-oriented approach compared to traditional date functions like date() and strtotime(). The DateTime class offers a wider range of methods for date manipulation, time zone handling, and formatting. However, the DateTime class can be slightly more verbose and complex to work with compared to the simplicity of traditional date functions.

// Using DateTime class to manipulate dates
$date = new DateTime('2022-01-01');
$date->modify('+1 day');
echo $date->format('Y-m-d');
