How can the current time be increased by one hour in PHP?

To increase the current time by one hour in PHP, you can use the `date()` function to get the current time, then use the `strtotime()` function to add one hour to it. Finally, you can format the new time using the `date()` function again.

$current_time = date('Y-m-d H:i:s');
$one_hour_later = date('Y-m-d H:i:s', strtotime($current_time . ' +1 hour'));
echo $one_hour_later;
