Are there any potential pitfalls to using the date() function for displaying time differences in PHP scripts?

One potential pitfall of using the date() function for displaying time differences in PHP scripts is that it only works with timestamps, so you would need to convert your time differences into timestamps before using date(). To solve this issue, you can use the DateTime class in PHP, which provides more flexibility and functionality for working with dates and times.

// Calculate time difference
$datetime1 = new DateTime('2022-01-01 12:00:00');
$datetime2 = new DateTime('2022-01-01 13:30:00');
$interval = $datetime1->diff($datetime2);

// Display time difference
echo $interval->format('%H hours %i minutes');
