What are some best practices for handling date manipulation in PHP?

When manipulating dates in PHP, it's important to use the DateTime class for accurate and reliable date calculations. This class provides a wide range of methods for manipulating dates, such as adding or subtracting days, months, or years, formatting dates, comparing dates, and more. By using the DateTime class, you can avoid common pitfalls and ensure your date manipulations are accurate and consistent.

// Example of using DateTime class for date manipulation
$today = new DateTime(); // Get current date and time
$nextWeek = $today->modify('+1 week'); // Add 1 week to current date
echo $nextWeek->format('Y-m-d'); // Output the date in 'YYYY-MM-DD' format
