What is the best practice for adding or subtracting days from a given date in PHP?

When adding or subtracting days from a given date in PHP, the best practice is to use the `DateTime` class. This class provides a clean and reliable way to manipulate dates and perform calculations easily. You can create a `DateTime` object with the initial date, then use the `modify()` method to add or subtract the desired number of days. 

// Create a DateTime object with the initial date
$date = new DateTime('2022-01-01');

// Add 5 days to the date
$date->modify('+5 days');

// Subtract 3 days from the date
$date->modify('-3 days');

// Output the final date
echo $date->format('Y-m-d');
