Are there any best practices for handling date calculations in PHP?

When handling date calculations in PHP, it is important to use the DateTime class, which provides a more robust and reliable way to work with dates and times. This class offers various methods for manipulating dates, such as adding or subtracting days, months, or years, as well as formatting dates in different ways. By using the DateTime class, you can ensure accuracy and avoid common pitfalls associated with date calculations in PHP.

// Example of handling date calculations using the DateTime class
$startDate = new DateTime('2022-01-01');
$endDate = $startDate->modify('+1 week');

echo $endDate->format('Y-m-d'); // Output: 2022-01-08
