What are the advantages and disadvantages of using MySQL versus PHP for date difference calculations?

When calculating date differences in MySQL, you can use built-in functions like DATEDIFF or TIMESTAMPDIFF, which can simplify the process. However, performing date calculations in PHP gives you more flexibility and control over the calculations.

// PHP code snippet for calculating date difference
$date1 = new DateTime('2022-01-01');
$date2 = new DateTime('2022-01-10');
$interval = $date1->diff($date2);
echo $interval->format('%R%a days');
