What are some best practices for storing and displaying date differences in PHP variables?

When storing and displaying date differences in PHP variables, it is best to use the DateTime class to calculate the difference between two dates and format it as needed. This allows for accurate calculations and easy manipulation of date values. Additionally, using the date_diff function can help in getting the precise date difference in days, months, or years. 

// Example of storing and displaying date differences in PHP variables

$date1 = new DateTime('2022-01-01');
$date2 = new DateTime('2022-02-15');

$interval = $date1->diff($date2);

echo $interval->format('%R%a days'); // Output: +45 days
